56f8347 technical data, rev.11 74 freescale semiconductor preliminary part 5 interrupt controller (itcn) 5.1 introduction the interrupt controller (itcn) m odule is used to arbitr ate between various inte rrupt requests (irqs), to signal to the 56800e core when an inte rrupt of sufficient priority exists , and to what address to jump in order to service this interrupt. 5.2 features the itcn module design includes these distinctive features: ? programmable priority levels for each irq ? two programmable fast interrupts ? notification to sim module to restar t clocks out of wait and stop modes ? drives initial address on the address bus after reset for further information, see table 4-5 , interrupt vector table contents. 5.3 functional description the interrupt controller is a slave on the ipbus. it contains registers allowing each of the 82 interrupt sources to be set to one of four pr iority levels, excluding certain inte rrupts of fixed priority. next, all of the interrupt requests of a given level are priority en coded to determine the lowest numerical value of the active interrupt requests for that level. within a give n priority level, zero is the highest priority, while number 81 is the lowest. 5.3.1 normal interrupt handling once the itcn has determined that an interrupt is to be serviced and which interrupt has the highest priority, an interrupt vect or address is generated. no rmal interrupt handling con catenates the vba and the vector number to determine th e vector address. in this way, an offset is generated into the vector table for each interrupt. 5.3.2 interrupt nesting interrupt exceptions may be nested to allow an irq of higher priori ty than the current exception to be serviced. the following tables define the ne sting requirements for each priority level. table 5-1 interrupt mask bit definition sr[9] 1 1. core status register bits indicating current interrupt mask within the core. sr[8] 1 permitted exceptions masked exceptions 0 0 priorities 0, 1, 2, 3 none 0 1 priorities 1, 2, 3 priority 0 1 0 priorities 2, 3 priorities 0, 1 1 1 priority 3 priorities 0, 1, 2
functional description 56f8347 technical data, rev.11 freescale semiconductor 75 preliminary 5.3.3 fast interrupt handling fast interrupts are described in the dsp56800e reference manual . the interrupt c ontroller recognizes fast interrupts before the core does. a fast interrupt is defined (to the itcn) by: 1. setting the priority of the interrupt as level 2, with the appropriate field in the ipr registers 2. setting the fimn register to the appropriate vector number 3. setting the fivaln and fivahn registers with the address of the code for the fast interrupt when an interrupt occurs, its vector number is compar ed with the fim0 and fim1 register values. if a match occurs, and it is a level 2 interrupt, the itcn handles it as a fast interrupt. the itcn takes the vector address from the appropriate fivaln and fivahn registers, instead of generating an addr ess that is an offset from the vba. the core then fetches the instruction from the indicated vector adddress and if it is not a js r, the core starts its fast interrupt handling. table 5-2. interrupt priority encoding ipic_level[1:0] 1 1. see ipic field definition in part 5.6.30.2 current interr upt priority level required nested exception priority 00 no interrupt or swilp priorities 0, 1, 2, 3 01 priority 0 priorities 1, 2, 3 01 priority 1 priorities 2, 3 11 priorities 2 or 3 priority 3
56f8347 technical data, rev.11 76 freescale semiconductor preliminary 5.4 block diagram figure 5-1 interrupt controller block diagram 5.5 operating modes the itcn module design contains two major modes of operation: ? functional mode the itcn is in this mode by default. ? wait and stop modes during wait and stop modes, the syst em clocks and the 56800e core are turned off. the itcn will signal a pending irq to the system integr ation module (sim) to restart the clocks and service the irq. an irq can only wake up the core if the irq is enabled pr ior to entering the wait or stop mode. also, the irqa and irqb signals automatically become low- level sensitive in these modes even if the control register bits are set to make them falling- edge sensitive. this is because there is no clock available to detect the falling edge. a peripheral which requires a clock to generate interrupts will not be able to generate interrupts during stop mode. the flexcan module can wake the device from st op mode, and a reset will do just that, or irqa and irqb can wake it up. priority level 2 -> 4 decode int1 priority level 2 -> 4 decode int82 level 0 82 -> 7 priority encoder any0 level 3 82 -> 7 priority encoder any3 int vab ipic control 7 7 pic_en iack sr[9:8]

overview 56f8347 technical data, rev.11 freescale semiconductor 103 preliminary part 6 system integration module (sim) 6.1 overview the sim module is a system catchall for the glue logic that ties together the system-on-chip. it controls distribution of resets and clocks and provides a number of control feat ures. the system integration module is responsible for the following functions: ? reset sequencing ? clock generation & distribution ? stop/wait control ? pull-up enables for selected peripherals ? system status registers ? registers for software access to the jtag id of the chip ? enforcing flash security these are discussed in more detail in the sections that follow. 6.2 features the sim has the following features: ? flash security feature prevents unauthorized ac cess to code/data contained in on-chip flash memory ? power-saving clock gating for peripheral ? three power modes (run, wait, st op) to control power utilization ? stop mode shuts down the 56800e core, system clock, peripheral clock, and pll operation ? stop mode entry can optionally disable pll and o scillator (low power vs. fast restart); must be explicitly done ? wait mode shuts down the 56800e core and unnecessary system clock operation ? run mode supports full part operation ? controls to enable/disable the 5680 0e core wait and stop instructions ? calculates base delay for reset exte nsion based upon por or reset operations. reset delay will be either 3 x 32 clocks for reset, except for por, which is 2^21 clock cycles. ? controls reset sequencing after reset ? software-initiated reset ? four 16-bit registers reset only by a power-on r eset usable for general-purpose software control ? system control register ? registers for software access to the jtag id of the chip
56f8347 technical data, rev.11 104 freescale semiconductor preliminary 6.3 operating modes since the sim is responsible for di stributing clocks and re sets across the chip, it must understand the various chip operating modes and ta ke appropriate action. these are: ? reset mode, which has two submodes: ? por and reset operation the 56800e core and all peripherals are reset. this occurs when the internal por is asserted or the reset pin is asserted. ? cop reset and software reset operation the 56800e core and all peripherals are reset. the ma bit within the omr is not changed. this allows the software to determine the boot mode (internal or external boot) to be used on the next reset. ? run mode this is the primary mode of opera tion for this device. in this mode, the 56800e co ntrols chip operation. ? debug mode the 56800e is controlled via jtag/eonce when in debug mode. all peripherals, except the cop and pwms, continue to run. cop is disabled and pwm outputs are optionally switched off to disable any motor from being driven; see the pwm chapter in the 56f8300 peripheral user manual for details. ? wait mode in wait mode, the core clock and memory clocks are disabled. optionally, the cop can be stopped. similarly, it is an option to switch off pwm output s to disable any motor from being driven. all other peripherals continue to run. ? stop mode when in stop mode, the 56800e core, memory, and most peripheral clocks are shut down. optionally, the cop and can can be stopped. for lowest power cons umption in stop mode, the pll can be shut down. this must be done explicitly before entering stop mode, since there is no automatic mech anism for this. the can (along with any non-gated interru pt) is capable of waking the chip up from stop mode, but is not fully functional in stop mode. 6.4 operating mode register figure 6-1 omr the reset state for mb a nd ma will depend on the fl ash secured state. see part 4.2 and part 7 for detailed information on how the operating mode register (omr) ma a nd mb bits operate in this device. for all other bits, see the dsp56800e reference manual . note: the omr is not a memory map regi ster; it is directly accessible in code through the acronym omr. bit 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 nl cm xp sd r sa ex 0 mb ma type r/w r/w r/w r/w r/w r/w r/w r/w r/w reset 00000000000000xx

56f8347 technical data, rev.11 120 freescale semiconductor preliminary finally, followed by a 32 clock window in which the core is initialized. after completion of the described reset sequence, application code will begin execution. resets may be asserted asynchronous ly, but are always released internally on a rising edge of the system clock. part 7 security features the 56f8347/56f8147 offer security features intended to prevent unauthorized users from reading the contents of the flash memory (fm) array. the flash security consists of several hardware interlocks that block the means by which an unauthorized user could gain access to the flash array. however, part of the security must lie with the user?s code. an extrem e example would be user?s code that dumps the contents of the internal program, as this code would defeat the purpose of security. at the same time, the user may also wi sh to put a ?backdoor? in his program. as an exampl e, the user downloads a security key through the sci, allo wing access to a programmi ng routine that updates parameters stored in another section of the flash. 7.1 operation with security enabled once the user has programmed the flash with his application code, the de vice can be secured by programming the security byt es located in the fm c onfiguration field, which o ccupies a portion of the fm array. these non-volatile bytes will keep the part secured through reset a nd through power-down of the device. only two bytes within this field are used to enable or disable security. re fer to the flash memory section in the 56f8300 peripheral user manual for the state of the security bytes and the resulting state of security. when flash security mode is enabled in ac cordance with the method described in the flash memory module specification, the de vice will disable exte rnal p-space accesses (disabling extboot = 1 mode), restrict memory and disable the core eo nce debug capabilities. no rmal program execution is otherwise unaffected. 7.2 flash access blocking mechanisms the 56f8347/56f8147 have several operat ing functional and test modes. effective flash security must address operating mode sele ction and anticipate modes in which the on-chip flash can be compromised and read without explicit user pe rmission. methods to block these are outlined in the next subsections. 7.2.1 forced operating mode selection at boot time, the sim determines in which func tional modes the device will operate. these are: ? internal boot mode ? external boot mode ? secure mode when flash security is enabled as described in the flash memory module specification, the device will boot in internal boot mode, disable all access to external p-space, and start executing code from the boot flash at address 0x02_0000.
flash access blocking mechanisms 56f8347 technical data, rev.11 freescale semiconductor 121 preliminary this security affords protection only to applications in which the device operates in internal flash security mode. therefore, the security feature cannot be used unless al l executing code resides on-chip. when security is enabled, any atte mpt to override the default intern al operating mode by asserting the extboot pin in conjunction wi th reset will be ignored. 7.2.2 disabling eonce access on-chip flash can be read by issui ng commands across the eonce port, which is the debug interface for the 56800e core. the trst , tclk, tms, tdo, and td i pins comprise a jtag interface onto which the eonce port functionality is mapped. when the device boots, the chip-l evel jtag tap (test access port) is active and provides the chip?s boundary s can capability and access to the id register. proper implementation of flash security requires that no acce ss to the eonce port is provided when security is enabled. the 56800e core has an input which disa bles reading of internal memory via the jtag/eonce. the fm sets this input at reset to a value determined by the contents of the fm security bytes. 7.2.3 flash lockout recovery if a user inadvertently enables fl ash security on the devi ce, a built-in lockout re covery mechanism can be used to reenable access to the devi ce. this mechanism completely reases all on-chip flash, thus disabling flash security. access to this recovery mechanism is built into codewarrior via an instruction in memory configuration ( .cfg ) files. add, or uncomment the following configuration command: unlock_flash_on_connect 1 for more information, please see codewarrior mc56f83xx/dsp5685x family targeting manual . the lockout_recovery instruction will have an associ ated 7-bit data register (dr) that is used to control the clock divider ci rcuit within the fm module. this divide r, fm_clkdiv[6:0], is used to control the period of the clock used for timed events in the fm erase algorithm. this re gister must be set with appropriate values before the lockout sequence can begin. refer to the jtag section of the 56f8300 peripheral user manual for more details on setting this register value. the value of the jtag fm_clk div[6:0] will replace th e value of the fm regist er fmclkd that divides down the system clock for time d events, as illustrated in figure 7-1 . fm_clkdiv[6] will map to the prdiv8 bit, and fm_clkdiv[5:0] will map to the div[5:0] bits. the combination of prdiv8 and div must divide the fm input clock down to a frequency of 150khz-200khz. the ?writing the fmclkd register ? section in the flash memory chapter of the 56f8300 peripheral user manual gives specific equations for calculati ng the correct values.
56f8347 technical data, rev.11 122 freescale semiconductor preliminary figure 7-1 jtag to fm connection for lockout recovery two examples of fm_clk div calculations follow. example 1: if the system clock is the 8mhz crystal frequency because the pl l has not been set up, the input clock will be be low 12.8mhz, so prdiv8 = fm_clkdiv[6] = 0. using the following equation yields a div value of 19 for a clock of 200khz, and a div value of 20 for a clock of 190khz. this translates into an fm_clkdiv[6:0] value of $13 or $14, respectively. example 2: in this example, the system clock has been set up with a value of 32mhz, making the fm input clock 16mhz. because that is greater than 12.8mhz, prdi v8 = fm_clkdiv[6] = 1. using the following equation yields a div value of 9 for a clock of 200khz, and a div value of 10 for a clock of 181khz. this translates to an fm_clkdiv[ 6:0] value of $49 or $4a, respectively. once the lockout_recovery instruction has been sh ifted into the instruct ion register, the clock divider value must be shifted into the corresponding 7- bit data register. after th e data register has been updated, the user must transition the tap controller into the r un-test/idle state for the lockout sequence to commence. the controller must remain in this state until the erase sequence has completed. for details, see the jtag section in the 56f8300 peripheral user manual . note: once the lockout recovery sequence has completed, the user must reset both the jtag tap controller (by asserting trst ) and the device (by asserting external chip reset) to re turn to normal unsecured operation. sys_clk jtag fmclkd divider 7 7 7 2 fm_clkdiv fm_erase flash memory clock input sys_clk (2) ) ( < < (div + 1) 150[khz] 200[khz] sys_clk (2)(8) ) ( < < (div + 1) 150[khz] 200[khz]
introduction 56f8347 technical data, rev.11 freescale semiconductor 123 preliminary 7.2.4 product analysis the recommended method of unsecuring a programmed device for product analys is of field failures is via the backdoor key access. the customer would need to supply technical support with the backdoor key and the protocol to acce ss the backdoor routine in the flash. a dditionally, the keyen bit that allows backdoor key access must be set. an alternative method for performing analysis on a s ecured microcontroller woul d be to mass-erase and reprogram the flash with the original code, but modify the security bytes. to insure that a customer does not inadvertently lo ck himself out of the devi ce during progr amming, it is recommended that he program the backdoor access key first, his applic ation code second, and the security bytes within the fm c onfiguration field last. part 8 general purpose input/output (gpio) 8.1 introduction this section is intended to supplemen t the gpio information found in the 56f8300 peripheral user manual and contains only chip-specific information. this information supe rcedes the generic information in the 56f8300 peripheral user manual . 8.2 memory maps the width of the gpio port defines how many bits are implemented in eac h of the gpio re gisters. based on this and the default function of each of the gpio pins, the re set values of the gpiox_pur and gpiox_per registers change from port to port. tables 4-29 through 4-34 define the actual reset values of these registers. 8.3 configuration there are six gpio ports defi ned on the 56f8347/56f8147. the width of each port and the associated peripheral function is shown in table 8-1 and table 8-2 . the specific mapping of gpio port pins is shown in table 8-3 . table 8-1 56f8347 gpio ports configuration gpio port port width available pins in 56f8347 peripheral function reset function a14 14 14 pins - emi address pins emi address b8 8 8 pins - emi address pins emi address c11 11 4 pins -dec1 / tmrb / spi1 4 pins -dec0 / tmra 3 pins -pwma current sense dec1 / tmrb dec0 / tmra pwma current sense

power consumption 56f8347 technical data, rev.11 freescale semiconductor 155 preliminary c, the internal [dynamic component], is classic c*v 2 *f cmos power dissipation corresponding to the 56800e core and standard cell logic. d, the external [dynamic component], reflects power dissipated on-chip as a result of capacitive loading on the external pins of the chip. this is also commonly described as c*v 2 *f, although simulations on two of the io cell types used on the device reveal that the power-versu s-load curve does have a non-zero y-intercept. power due to capacitive loading on output pins is (first order) a f unction of the capacitive load and frequency at which the outputs change. table 10-25 provides coefficients for calculating power dissipated in the io cells as a function of capacitive load. in these cases: totalpower = ((intercept +slope*cload)*frequency/10mhz) where: ? summation is performed over all ou tput pins with capacitive loads ? totalpower is expressed in mw ? cload is expressed in pf because of the low duty cycle on most device pins , power dissipation due to capacitive loads was found to be fairly low when averaged ove r a period of time. the one possible exception to this is if the chip is using the external address and data buses at a rate approaching the maximum system rate. in this case, power from these buses can be significant. e, the external [static component], reflects the effects of placing resistive load s on the outputs of the device. sum the total of all v 2 /r or iv to arrive at the resistive load contribution to power. assume v = 0.5 for the purposes of these rough ca lculations. for instance, if there is a total of 8 pwm outputs driving 10ma into leds, then p = 8*.5*.01 = 40mw. in previous discussions, power consum ption due to parasitics associated with pure input pins is ignored, as it is assumed to be negligible. table 10-25 i/o loading coefficients at 10mhz intercept slope pdu08dgz_me 1.3 0.11mw / pf pdu04dgz_me 1.15mw 0.11mw / pf

thermal design considerations 56f8347 technical data, rev.11 freescale semiconductor 167 preliminary part 12 design considerations 12.1 thermal desi gn considerations an estimation of the chip junction temperature, t j , can be obtained from the equation: t j = t a + (r j x p d ) where: the junction-to-ambient thermal resi stance is an industry-standard va lue that provides a quick and easy estimation of thermal perf ormance. unfortunately, there are two values in common usage: the value determined on a single-layer board and the value obtained on a board wi th two planes. for packages such as the pbga, these values can be different by a factor of two. which value is closer to the application depends on the power diss ipated by other components on the board. the value obtained on a single-layer board is appropriate for the tightly packed printed circuit board. the va lue obtained on the board with the internal planes is usually appropriate if the board has low-power dissipation and the components are well separated. when a heat sink is used, the thermal resistance is expressed as the sum of a junction-to-case thermal resistance and a case-to-ambient thermal resistance: r j = r jc + r c where: r jc is device-related and cannot be influenced by the us er. the user controls th e thermal environment to change the case-to-ambient thermal resistance, r ca . for instance, the user can change the size of the heat sink, the air flow around the device, the interface mate rial, the mounting arrange ment on printed circuit board, or change the thermal dissipation on th e printed circuit board surrounding the device. to determine the junction temperature of the device in the application when heat sinks are not used, the thermal characterization parameter ( jt ) can be used to determine th e junction temperature with a measurement of the temperature at the top center of the package case using the following equation: t j = t t + ( jt x p d ) where: t a = ambient temperature for the package ( o c) r j = junction-to-ambient thermal resistance ( o c/w) p d = power dissipation in the package (w) r ja = package junction-to-ambient thermal resistance c/w r jc = package junction-to-case thermal resistance c/w r ca = package case-to-ambient thermal resistance c/w t t = thermocouple temperature on top of package ( o c) jt = thermal characteri zation parameter ( o c)/w p d = power dissipation in package (w)
56f8347 technical data, rev.11 168 freescale semiconductor preliminary the thermal characterization parameter is measured per jesd51-2 specification using a 40-gauge type t thermocouple epoxied to the top ce nter of the package case. the th ermocouple should be positioned so that the thermocouple junction re sts on the package. a small amount of epoxy is placed over the thermocouple junction and over about 1mm of wire extending from the junction. the thermocouple wire is placed flat against the package case to avoid measurement errors caused by cooling effects of the thermocouple wire. when heat sink is used, the junction temperature is determined from a ther mocouple inserted at the interface between the case of the p ackage and the interface material. a clearance slot or hole is normally required in the heat sink. minimizing the size of the clearan ce is important to mi nimize the change in thermal performance caused by removing part of the thermal interface to the heat sink. because of the experimental difficulties with th is technique, many engine ers measure the heat si nk temperature and then back-calculate the case temperatur e using a separate measurement of the thermal resistance of the interface. from this case temperat ure, the junction temperature is de termined from th e junction-to-case thermal resistance. 12.2 electrical design considerations use the following list of considerations to assure correct device operation: ? provide a low-impedance path from the board power supply to each v dd pin on the device, and from the board ground to each v ss (gnd) pin ? the minimum bypass requirement is to place six 0.01?0.1 f capacitors positioned as close as possible to the package supply pins. the recomm ended bypass configuration is to place one bypass capacitor on each of the v dd /v ss pairs, including v dda /v ssa. ceramic and tantalum capacitors tend to provide better performance tolerances. ? ensure that capacitor leads and associated prin ted circuit traces that connect to the chip v dd and v ss (gnd) pins are less than 0.5 inch per capacitor lead ? use at least a four-layer printed circui t board (pcb) with two inner layers for v dd and v ss ? bypass the v dd and v ss layers of the pcb with approximately 100 f, preferably with a high-grade capacitor such as a tantalum capacitor caution this device contains protective circuitry to guard against damage due to high static voltage or electrical fields. however, normal precautions are advised to avoid application of any voltages higher than maximum-rated voltages to this high-impedance circuit. reliability of operation is enhanced if unused inputs are tied to an appropriate voltage level.
power distribution and i/o ring implementation 56f8347 technical data, rev.11 freescale semiconductor 169 preliminary ? because the device?s output signals have fast rise and fall times, pcb trace lengths should be minimal ? consider all device loads as well as parasitic capacitance due to pcb traces when calculating capacitance. this is especially critical in system s with higher capacitive loads that co uld create higher transient currents in the v dd and v ss circuits. ? take special care to minimize noise levels on the v ref , v dda and v ssa pins ? designs that utilize the trst pin for jtag port or eonce module functionality (such as development or debugging systems) should allow a means to assert trst whenever reset is asserted, as well as a means to assert trst independently of reset . designs that do not require debugging functionality, such as consumer products, should tie these pins together. ? because the flash memory is programmed through the jtag/eonce port, the designer should provide an interface to this port to allo w in-circuit flash programming 12.3 power distribution and i/o ring implementation figure 12-1 illustrates the general power control incorporated in the 56f8347/56f8147. this chip contains two internal power regulators. one of them is powered from the v dda_osc_pll pin and cannot be turned off. this regul ator controls power to the internal cl ock generation circuitr y. the other regulator is powered from the v dd_io pins and provides power to all of the internal digi tal logic of the core, all peripherals and the internal memo ries. this regulator can be turned off, if an external v dd_core voltage is externally applied to the v cap pins. in summary, the entire ch ip can be supplied from a single 3.3 volt supp ly if the large core regulator is enabled. if the regulator is not enabled, a dual supply 3.3v/2.5v configurat ion can also be used. notes: ? flash, ram and internal logic are powered from the core regulator output ?v pp 1 and v pp 2 are not connected in the customer system ? all circuitry, analog and digital, shares a common v ss bus figure 12-1 power management reg core v cap i/o adc v dd v ss reg v dda_osc_pll osc v ssa_adc v dda_adc v refh v refp v refmid v refn v reflo
