d8, d(l) = d7 ? d0, and c = c7 ? c0. in the case of a command with no data, you only need to input the command byte. when data input is finished, a pulse at mlt is generated to indicate that the command transmission is finished. from then on, command is decoded and carried out. the sense output shows ready (/busy) status at default. in other words, it is "l" when it receives a command, and "h" when the command is completed. in certain commands, sense output has a meaning other than that of ready. for example, it can show the "on/off" information of the limit switch or the presence of a disc. the detailed input timing of S5L9232 is shown in figure 2. micro-controller sends mdt to mck falling edge, in the order of msb, data, and command. S5L9232 latches the data at mck's rising edge. micro-controller no longer sends mck when the transmission of all mdt is finished. at this time, mlt becomes "l" to indicate that the transmission of command and data from micro-controller to S5L9232 is complete. mlt mdt ~ ~ mlt ~ ~ ~ ~ ~ ~ d7 d6 d5 d1 latch figure 2. micro-controller to S5L9232 input timing compart disc player S5L9232 17 the timing for sending data to micro-controller is shown in figure 3. in such a case the digital servo signal processor (dssp) stores the data to be sent to micro-controller after command has been carried out, in the output buffer. at the same time, it makes the sense output "h" to indicate that the dssp's command processing routine is finished. if micro-controller needs to read the response data, only mck is sent to S5L9232. S5L9232 then sends the output serially through sense to micro-controller, at mck's falling edge. since sense's ssel (serial data select signal) is "1", the data in the output buffer should be output. the output to sense is carried out in units of byte, and in the order of r(h) = r15 ? r8 and r(l) = r7 ? r0, starting with msb. mck sense ~ ~ ~ ~ ~ ~ r15 r14 r13 r1 r0 ssel = 1 figure 3. S5L9232 to micro-controller output timing S5L9232 generates one sense signal that makes the cd-dsp and servo into a single chip and goes through mux to micro-controller. hence, micro-controller can use sense as a direct input signal. as shown in table 1 and table 2, micro-controller command can be divided into micro-controller command for digital servo (00 ? 5fh), and micro-controller command for cd-dsp (60h ? ffh) S5L9232 compart dis c player 18 micro-controller command set table 1. servo part micro-controller command set data init. addr. cmd d15 d14 d13 d12 d11 d10 d9 d8 sense value d7 d6 d5 d4 d3 d2 d1 d0 00 stpcmd /busy -

S5L9232 supports only the msb first micro-controller command input format. in the micro-controller command table, italics means active low; '0' specified locations must be set to '0' when the command is used, and empty location is defined as 'don't care.' S5L9232 compart dis c player 24 stpcmd (address 00h) the stpcmd stops the execution of jmpcmd (05h) or automatic adjustment related servo operations, or changes the operations to the stop mode. it also reduces the operating speed of embedded digital signal processor to save power consumption, turns on/off the laser diode, and clears the control/measurement data. the following descriptions of 4bit constant data are assigned. name code dh d15 d14 d13 d12 d11 d10 d9 d8 stpcmd 00 dl d7 d6 d5 d4 d3 d2 d1 d0 ldx idle abrt stop .stop : stop mode. this command can be activated in any mode. this command reserve the stop until the mon signal turns off. however, if the stopcmd (0080h) is re-executed while stop is being reserved, it immediately executes the stop regardless of the mon condition. "0" : no execution. executes next(abrt) bit check. "1" : reserves the stop mode. .abrt : stops track searchi ng and automatic control operation and returns to the previous state "0" : no execution. executes idle bit check. "1" : stops the jumping and control and returns to the previous state this command should not be used with 11h, 14h, 15h commands. we recommend that 11h, 14h, 15h command be used with stop(d8) for the same operation. .idle : sets to the idle (power save mode). ram data remains. "0" : returns to normal mode from the idle mode. "1" : sets to idle mode. .ldx : turns the laser diode on an d off. "0" : laser diode off "1" : laser diode on the priority order of the data bits is stop, abrt, and idle and ldx are equal priority. if the higher priority bits are "1", the idle and ldx bits are not checked. all rams are cleared only when stop=abrt = 1. although the ram can be cleared using the normal stpcmd, in this case, the automatically controlled value and measurement are not cleared so that the servo can be immediately turned on without re-control in the next play. however, if the disc is changed, these values must be cleared. because it is best to start from the beginning when the disc is changed, the control values should be cleared using the stpcmd options. in the idle mode, the embedded digital signal processor's speed becomes 1/256, reducing the power consumptions. the idle and ldx bits can be accepted only when the servo is off. if another action command is to be used before the execution of the automatic control command completes, the command must be first aborted using the stpcmd. compart disc player S5L9232 25 ddtcmd (address 01h) the ddtcmd checks for the presence of the disc and outputs the result, and it simultaneously measures the offset. it can also control both the focus error input gain and focus balance. before it performs the focus search, it automatically turns on the laser diode. the auto mode, which automatically uses the triangular waveform, and micro-controller manual mode can be used for the focus search. the speed is controlled through fps2 ? 0 in either mode. the focus actuator should be moved faster during disc detection compare with focus pull-in to determine if the disc is present. (the focus is not pulled-in.) it can read the data that indicates the type and presence of the disc. name code dh d15 d14 d13 d12 d11 d10 d9 d8 ddtcmd 01 dl d7 d6 d5 d4 d3 d2 d1 d0 auto updn figa fbal rpt fsp2 fsp1 fsp0 ./auto ./updn : sets focus search mode. 0 0 : auto mode. sense output indicates busy(l)/ready(h). 0 1 : auto mode. automatically executes to focus pull-in ddtcmd's search 1 0 : manual up mode(actuator up). actuator(fzc) signal is output through sense. 1 1 : manual down mode(actuator down). actuator(fzc) signal is output through sense. ./figa : the focus input gain is changed by the fe peak level. because the input gain reference changes in every control, control must be completed with one try.

S5L9232 compart dis c player 98 ? connect data work area this is an area of memory reserved for connect data. this area is 2k bits if using 1m drams, 4k bits if using 4m drams, or 8k bits if using 16m drams. ra wa vwa connect data work area valid data area ram addresses vwa (valid write address) the vwa is determined according to the s0s1 and waqv command. refer to the timing chart below. 1. s0s1 is a 75hz clock when used for normal read mode and it is a 150hz clock when used for double-speed read mode, synchronized to the cd format block start timing. when this clock goes low, wa which is the write address of internal encode sequence, is stored (see note 2). 2. the micom checks the subcode and, if confirmed to be correct, generates a waqv command ($80). 3. when the waqv command is received, the previously latched wa is stored as the vwa. notes 2: actually, there is a small time difference, or gap, between the input data and yblkck. this gap serves to preserves the preceding wa to protect against incorrect operation. 13.3ms vwa latch set waqv set vwa(x) vwa(x + 1) s0s1 micom command set refer to micom interface vwa values shown are for rate fs. the values are 1/2 those shown at rate 2fs. figure 3. yblkck and vwa relationship compart disc player S5L9232 99 yflag, flag6 correct data demodulation becomes impossible for the cd-dsp when a disturbance exceeding the ram jitter margin occurs. the yflag signal input pin is used to indicate when such a condition has occurred. the ic checks the yflag input and stops the encode sequence when such a disturbance has occurred, and then makes flag6 active. compare-connect sequence the sm5910 supports three kinds of connect modes; 3-pair compare-connect, 2-pair compare-connect and direct connect. note that the sm5910 can also operate in 12-bit comparison connect mode using only the most significant 12 bits of data for connection operation. in 3-pair compare-connect mode, the final 6 valid data (3 pairs of left- and right-channel data input before encode processing) and the most recently input data are compared until three continuous data pairs all conform. at this point, the encode sequence is re-started and data is written to vwa. in 2-pair compare-connect mode, comparison occurs just as for 3-pair comparison except that only 2 pairs from the three compared need to conform with the valid data. at this point, the encode sequence is re-started and data is written to vwa. in direct-connect mode, comparison is not performed at all, and encode sequence starts and data is written to the vwa. this mode is for systems that cannot perform compare-connect operation. ? compare-connect preparation time 1. comparison data preparation time internally, when the compare-connect start command is issued, a sequence starts to restore the data for comparison. the time required for this preparation after receiving the command is approximately 2.5 x (1/fs). (approximately 60 ms when fs = 44.1khz) 2. after the above preparation is finished, data is input beginning from the left-channel data and comparison starts. 3. if the compare-connect command is issued again, the preparation time above is not necessary and operation starts from step 2. 4. the same sequence takes place in direct-connect mode also. however, at the point when 3 words have been input, all data is directly connected as if comparison and conformance had taken place. ? compare-connect sequence stop if a compare-connect stop command (80h with msdcn1= 1, msdcn2= 0) is input from the microcontroller, compare-connect sequence stops. if compare-connect sequence was not operating, the compare-connect stop command performs no operation. however, make sure that the other bit settings within the same 80h command are valid. S5L9232 compart dis c player 100 encode sequence temporary stop ? when ram becomes full, mswren is set low using the 80h command and encode sequence stops. (for details of the stop conditions, refer to the description of the encod flag.) ? then, if mswren is set high without issuing a compare-connect start command, the encode sequence re- starts. at this time, new input data is written not to vwa, but to wa. in this way, the data already written to the region between vwa and wa is not lost. ? but if the mswren is set high (80h command) after using the compare-connect start command even only once, data is written to vwa. if data is input before comparison and conformance is detected, the same operation as direct-connect mode takes place when the command is issued. after comparison and conformance are detected, no operation is performed because the encode sequence has already been started. however, make sure that the other bit settings within the same 80h command are valid. dram refresh ? dram initialization refresh a 15-cycle ras-only refresh is carried out for dram initialization under the following conditions. when mson changes from 0 to 1 using command 80h. when from mson=1, msrden=0 and mswren=0 states only mswren changes to 1. in this case, encode sequence immediately starts and initial data is written (at 2fs rate input) after a delay of 0.7ms. ? refresh during shock-proof mode operation in this ic, a data access operation to any address also serves as a data refresh. accordingly, there are no specific refresh cycles other than the initialization refresh cycle (described above). this has the resulting effect of saving on dram power dissipation. a data access to dram can occur in an encode sequence write operation or in a decode sequence read operation. write sequence write operation stops during a connect operation whereas a read sequence read operation always continues while data is output to the d/a. the refresh rate for each dram during decode sequence is shown in the table below. the decode sequence, set by mson=1 and msrden=1, operates when valid data is in dram (when msemp=0). ? when mson=0, dram is not refreshed because no data is being accessed. although mson=1, dram is not refreshed if encod=0 and decod=0 (both encode and decode sequence are stopped). table 4. decode sequence refresh rate data compression mode dram used(same for 1 or 2 drams) 1m(256k x 4 bit) 4m(1m x 4 bit) 16m(4m x 4 bit) 4 bit 5.44ms 10.88ms 21.77ms 5 bit 4.35ms 8.71ms 17.42ms 6 bit 3.63ms 7.26ms 14.52ms full bit 1.36ms 2.72ms 5.81ms compart disc player S5L9232 101 selecting compression mode even when the compression mode in selected with the 85h command during shock-proof operation, no malfunction occurs. the compression mode change is not performed immediately after input of the 85h command, but it is performed at the following timing. wa cas ra cas encode compression mode decode compression mode ymld when 85h generated note: cas-000 is connect data. through-mode operation if mson is set low (80h command), an operating mode that does not perform shock-proof functions becomes active. in this case, input data is passed as-is (after attenuator and mute operations) to the output. external dram is not accessed. ? in this case, input data needs to be at a rate fs and the input word clock must be synchronized to the clk input (384fs). however, short range jitter can be tolerated (jitter-free system). ? jitter-free system timing starts from the first ylrck rising edge after either (a) a reset (nreset= 0) release by taking the reset input from low to high or (b) by taking mson from high to low. accordingly, to provide for the largest possible jitter margin, it is necessary that the ylrck clock be at rate fs by the time jitter-free timing starts. the jitter margin is 0.2/ fs (80 clock cycles). this jitter margin is the allowable difference between the system clock (clk) divided by 384 ( fs rate clock) and the ylrck input clock. if the timing difference exceeds the jitter margin, irregular operation like data being output twice or, conversely, incomplete data output may occur. in the worst case, a click noise may also be generated. when switching from shock-proof mode to through mode, an output noise may be generated, and it is therefore recommended to use the ydmute setting to mute zsrdata until just before data output. S5L9232 compart dis c player 102 attenuation ? the attenuation register is set by the 84h command. ? the attenuation register set value becomes active when the 83h command sets the att flag to 1. when the att flag is 0, the attenuation register value is considered to be the equivalent of 256 for a maximum gain of 0 db. ? the gain (db) is given from the set value ( datt) by the following equation. gain = 20 ?a log(datt/256) [db]; left and right channels ? for the maximum attenuation register set value ( datt = 255), the corresponding gain is -0.03 db. but when the att flag is 0 ( datt = 256), there is no attenuation. ? after a system reset initialization, the attenuation register is set to 64 (-12 db). however, because the att flag is reset to 0, there is no attenuation. ? when the attenuation register setting changes or when the att flag changes, the gain changes smoothly from the previous set gain towards the new set value. if a new value for the attenuation level is set before the previously set level is reached, the gain changes smoothly towards the latest setting. the gain changes at a rate of 4 ?h (1/fs) per step. a full-scale change (255 steps) takes approximately 23.3 ms (when fs = 44.1 khz). see figure 3. set 3 gain set 5 set 1 set 4 set 2 time figure 5. attenuation operation example soft mute soft mute operation is controlled by the soft flag using a built-in attenuation counter. mute is on when the soft flag is 1. when on, the attenuation counter output decrement by 1 step at a time, thereby reducing the gain. complete mute takes 1024/fs (or approximately 23.2 ms for fs = 44.1khz). conversely, mute is released when the soft flag is 0. in this case, the attenuation counter instantaneously increases. the attenuation register takes on the value when the att flag was 1. if the att flag was 0, the new set value is 256 (0 db). 256 step / 1024t s soft attenation level or full scale (gain) 8 figure 6. soft mute operation example compart disc player S5L9232 103 force mute serial output data is muted by setting the ydmute pin input high or by setting the mute flag to 1. mute starts and finishes on the leading left-channel bit. when mson is high and valid data is empty (msemp=h), the output is automatically forced into the mute state. 12-bit comparison connection when the cmp12 flag is set to 1, the least significant 4 bits of the 16-bit comparison connection input data are discarded and comparison connection is performed using the remaining 12 bits. note that if the cmp12 flag is set to 1 during a comparison connection operation, only the most significant 12 bits are used for comparison connection from that point on.

using q data initially, q1 to q80 are set using the 87h command, the dit flag is set using the 86h command, and then data is output from dit according to the digital audio interface format. q81 to q96 data are not required as these are set internally by crc calculation. there are 2 q data buffers; a data output buffer and a data storage buffer. as a result, after all data has been specified in the first data write, only that data that has changed needs to be written during the 2nd and subsequent data write operations. note that address 1001 is the write stop command and is, therefore, required after every data write operation. when space becomes available in the data output buffer, qrdy is set to 1 (91h command status bit s3) to indicate available space and then the contents of the data storage buffer are transferred to the data output buffer. after data is transferred, a data write to address 1001 (write stop command) resets the qrdy flag to 0. the q data buffer read access time for a complete data cycle is approximately 13.3 ms. audio channel status the channel status are information bits transferred to indicate the audio sample data length, preemphasis, sampling frequency, time code, source number, destination code, and other information. seven bits comprising cp1, cp2, lbit, and ctl0 to ctl3 can be set. all other bits are fixed. 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0 ctl0 ctl1 ctl2 ctl3 0 0 0 0 0 0 0 0 0 0 0 lbit 16 0 0 0 0 l=1 r=1 0 0 0 0 0 0 cp1 cp2 0 0 32 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 48 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 64 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 80 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 96 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 112 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 128 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 144 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 160 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 176 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 S5L9232 compart dis c player 106 subframe parity the parity bit is used to indicate the detection of an odd number of bit errors. it is set to 1 if the number of 1s in the digital audio interface 27-bit data is odd, and is set to 0 if the number of 1s is even. the 27-bit data plus parity bit form 28-bit data that always has an even number of 1s. dbb caution : it is only the case of funcntl($a0) dbbon=1 that this commands is effective. $70 : dbb related commands(70h = 0111 0000) name code dl7 dl6 dl5 dl4 init dbb 70 00h dl3 dl2 dl1 dl0 tst1 0 max dbb .tst1 : "0" : normal mode "1" : dbb test mode .max .dbb : 0 0 : dbb off (through) 0 1 : dbb on, minimum boost setting 1 0 : dbb off (through) 1 1 : dbb on, maximum boost setting the dbb (dynamic bass boost) function emphasizes the spectrum by changing gain of the specific frequency of the input signal. compart disc player S5L9232 107 dbb frequency characteristic S5L9232 compart dis c player 108 dbb gain response -90 -80 -70 -60 -50 -40 -30 -20 -10 0 -90 -80 -70 -60 -50 -40 -30 -20 -10 0 input [db] output [db] compart disc player S5L9232 109 digital servo digital servo the architecture of focus/tracking loop filter is as following. they have 3 poles and 3 zeros. k0 fein (tein) d k1 k2 d k3 k4 k5 d k6 d nsk 2 n fo (to) therefore, transfer function is as below. h(z) = k0 * (1-k1*z -1 ) * (1-k3 * z -1 ) * (1-k5* z -1 ) * (nsk*2 n ) (1-k2*z -1 ) * (1-k4 * z -1 ) * (1-k6* z -1 ) each coefficient could be changed variously depending on the characteristics of pick-up by micro-controller command. the filter coefficients can be designed using the provided simulator. using the simulator, users can monitor the closed loop characteristics of the full system, which includes actuator, rf, digital servo, and driver. if user selects only the frequencies of pole and zero, and the dc gain, simulator generates hexadecimal value of each coefficient automatically. focus servo the below figure is the functional block diagram of the focus servo. adc loop filter agc disturbance variable gain amp pwm micom command control focus search signal fe dfct fodf fodr the focus error signal input into the fe pin goes through the input gain adjustment amplifier to achieve a regular level. the signal passes through the adc, loop filter, and output gain control block, then is output to the fodf/fodr pin through the pwm. it activates the focus coil through the drive amplifier. for drop out solution, it holds the loop filters input if dfct signal is generated by the rf. if it receives the disc detect command (ddt) or focus on command (fon), it generates delta waves from inside the digital servo, which activates the focus coil to move the pick-up perpendicular to the disc. the output always passes through the noise-shaping filter to improve output resolutions. S5L9232 compart dis c player 110 when foncmd is asserted from micro-controller, fodf/fodr generates focus actuator drive voltage to monitor the fe signal, which carries out focus pull-in. focus-related jobs are divided into disc detection and focus pull-in. these are activated by ddtcmd and fon cmd command routines. tracking servo the below figure is the block diagram of tracking servo. adc loop filter agc disturbance variable gain amp pwm rev/fwd fe mirr trdf trdr dfct tzc sled servo after a/d, the te signal goes through the compensation filter and variable gain control block. it is then converted to pwm signal, then output to the driver ic (variable gain is automatically selected during auto gain adjustment). as drop out solution, it holds the loop filter input for dfct signal. when toncmd is input from micro-controller, the digital servo activates tracking filter, monitors mirr and tzc signals, and carries out pull-in of the closest track. like the focus servo, the tracking servo signals also come out through the noise-shaping filter. automatic adjustment the following adjustments are included in the automatic adjustments, which are offset adjustment by ofacmd, focus bias adjustment by fbacmd, tracking bias/balance adjustment by tbacmd, and loop gain adjustment by fgacmd and tgacmd. please refer to the micro-controller command specification for detail. the automatically adjusted features in order are as follows. compart disc player S5L9232 111 1) input gain adjustment this function is to measure the input error signal's peak level, then to adjust the input amplifier's gain to make the peak level about 80% of the a/d s maximum input. the input gain's automatic adjustment has the ability to absorb the deviation of the focus and tracking error's signal level from the rf for each set. also, there is no gain switching feature for different disc types within the rf, it corrects the focus and tracking error's signal level difference. for focus, the s_curve size measured during focus search is used as the input gain amp's input. for tracking, the te's track zero cross size when the disc is spinning in off track status is used as the input gain amp's input. automatic adjustment is carried out so that it is approximately 80% of the maximum input no matter what the input gain amplifier's output level is. this has the advantage of using the adc's input range to its fullest, and improving the decomposition ability in quantization. manual setting can set the input gain to a fixed value at an appropriate level 0 0 10 20 30 40 50 60 70 7f input peak value (before input gain control) output peak value (after input gain control) 10 20 30 40 50 60 70 7f figure 9. input gain adjustment amplifier's gain characteristics (for automatic adjustment) 2) offset adjustment the focus/tracking offset is electrical offset, which signifies the error level during defocus. the offsets can be explained as the error signals when there is no input (fe/ te's electrical offset). the offset measurement can be carried out during laser diode on/off status by micro-controller command, so it is appropriate to issue the system select command after reset release at the end. when ofacmd is received, the focus and tracking error offset are measured/averaged and stored in the register. this is to use the values during later filter operations in order to eliminate remaining error offset. 3) bias/balance adjustment two algorithms are used for adjustment of focus bias in this digital servo. one of them is making peak and bottom of the s-curve's amplitude same using the disc detect command ( ddtcmd), which is the one already mentioned. the other algorithm is the method in which the te sum(tes) level becomes peak, which is supported by fba cmd. the former is a rather simplified method that adjusts the bias as well as the ddtcmd search. the latter is a more active method that uses the following characteristic. if the balance is bad, the focus does not match exactly in the pit, and the tes level becomes lower, whereas when the focus is exact, the tes level goes to peak.
