384 output column driver PCF8832 7.17 ddram addressing data is written byte-wise into the ram matrix of the PCF8832 as illustrated in fig.11. the display ram has a matrix of 168 128 9 bits. ram locations are addressed by the address pointers. the address ranges are x = 0 to x = 127 (7f) and y = 0 to y = 167 (a7h). addresses outside of these ranges are not allowed. before writing to the ram, a window must be defined into which it can be written. the window is programmable via the command registers with xs and ys designating the start address, and xe and ye designating the end address. if, for example, the whole display content is to be written, the window is defined by the following values: xs = 0 (0h), ys = 0 (0h), xe = 127 (7fh) and ys = 159 (9fh). in vertical addressing mode (v = 1), the y-address increments after each byte. after the last y-address (y = ye), y wraps around to ys and x increments to address the next column. in horizontal addressing mode (v = 0), the x-address increments after each byte. after the last x-address (x = xe), x wraps around to xs and y increments to address the next row. after the very last address (x = xe and y = ye) the address pointers wrap around to address (x = xs and y = ys). for flexibility in handling a wide variety of display architectures, the commands ram data addressing and data control define flags mx, my and l, which allows mirroring of the x and y-addresses and selection of landscape or portrait mode. all combinations of flags are allowed. the available combinations of writing to the display ram are shown in figs 12 to 17. when mx, my, v or l are changed, the data must be rewritten to the display ram. handbook, full pagewidth mgw668 0 xe xs ys ye 1 2 3 4 5 6 7 167 127 0 y address x address r2 r1 r0 g2 g1 g0 bi2 bi1 bi0 r2 r1 r0 g2 g1 g0 b1 b0 d7 d6 d5 d4 d3 d2 d1 d0 display byte sent via interface pixel information stored in display ram d7 d6 d5 d4 d3 d2 diii dii di rgb fig.11 ram format and addressing. 2002 aug 16 17 philips semiconductors preliminary speci?cation stn rgb -

384 output column driver PCF8832 11.1.2 r ead mode ( only command register ) the read mode of the interface means that the microcontroller reads data from the PCF8832. to do so, the microcontroller first sends a command sequence, the PCF8832 then responds by transmitting data on the sdo line. after that, sce is required to go high (see fig.39) and this resets the rsta bit to write operation. the PCF8832 samples the sdi data at rising edges, but shifts sdo data at falling sclk edges. thus the microcontroller should read sdo data at rising sclk edges. after the read command sequence has been sent, the sdi line must be set to 3-state not later than the falling sclk edge of the last bit (see fig.39). handbook, full pagewidth sce sdi sdo d/c sclk b7 b6 b5 b4 b3 b2 b1 b0 b7 b6 b5 b4 b3 b2 b1 b0 b7 b6 b5 b4 b3 b2 b1 b0 b7 b6 b5 b4 b3 b2 b1 b0 cb (adr [ 5:0 ] = 01h) s rv (set rsta = 1) cb (set read adr = n) rv (from adrn) p mgw712 fig.39 serial bus protocol, read from register. 2002 aug 16 41 philips semiconductors preliminary speci?cation stn rgb - 384 output column driver PCF8832 11.2 serial interface (3-line) the serial interface is also a 3-line bidirectional interface for communication between the microcontroller and the lcd driver chip. the three lines are: sce (chip enable), sclk (serial clock) and sdi/sdo (serial data). 11.2.1 w rite mode the interface write mode means that the microcontroller writes commands and data to the PCF8832. each data packet contains a control bit d/ c and a transmission byte. if d/ c is low, the byte that follows is interpreted as a control byte. the basic and the advanced protocols are supported. the command set is given in table 6. if d/ c is high, the byte that follows is stored in the display data ram. after every data byte the address counter is incremented automatically. the serial interface is initialized when sce is high. in this state, sclk clock pulses have no effect and no power is consumed by the serial interface. a falling edge on sce enables the serial interface and indicates the start of data transmission. serial bus protocol (see fig.41): when sce is high, sclk clocks are ignored. during the high time of sce, the serial interface is initialized. at the falling edge of sce, sclk must be low sdi is sampled on the rising edge of sclk d/ c indicates whether the byte is a command (d/ c=0) or ram data (d/ c = 1); d/ c is sampled with the first rising edge of sclk if sce stays low after the last bit of a command/data byte, the serial interface expects the d/ c bit of the next byte at the next rising edge of sclk a reset pulse with res interrupts the transmission (the data being written into the ram may be corrupted); the registers are cleared, then if sce is low after the rising edge of res, the serial interface is ready to receive the d/ c bit of a command/data byte. handbook, full pagewidth mgw713 transmission byte d7 d6 d5 d4 d3 d2 d1 d0 msb lsb transmission byte (1) d/c transmission byte d/c d/c transmission byte d/c fig.40 serial data stream, write mode.

384 output column driver PCF8832 12.1.3 s tart and stop conditions both data and clock lines remain high when the bus is not busy (see fig.48). a high-to-low transition of the data line, while the clock is high is defined as the start condition (s). a low-to-high transition of the data line while the clock is high is defined as the stop condition (p). handbook, full pagewidth mbc622 sda scl p stop condition sda scl s start condition fig.48 definition of start and stop conditions. 12.1.4 a cknowledge each byte of eight bits is followed by an acknowledge bit (see fig.49). the acknowledge bit is a high signal put on the bus by the transmitter during which time the master generates an extra acknowledge related clock pulse. a slave receiver which is addressed must generate an acknowledge after the reception of each byte. also a master receiver must generate an acknowledge after the reception of each byte that has been clocked out of the slave transmitter. the device that acknowledges must pull-down the sda line during the acknowledge clock pulse, so that the sda line is stable low during the high period of the acknowledge related clock pulse (set-up and hold times must be taken into consideration). a master receiver must signal an end of data to the transmitter by not generating an acknowledge on the last byte that has been clocked out of the slave. in this event the transmitter must leave the data line high to enable the master to generate a stop condition. handbook, full pagewidth mbc602 s start condition 9 8 2 1 clock pulse for acknowledgement not acknowledge acknowledge data output by transmitter data output by receiver scl from master fig.49 acknowledge on the i 2 c-bus. 2002 aug 16 48 philips semiconductors preliminary speci?cation stn rgb - 384 output column driver PCF8832 12.2 i 2 c-bus hs-mode protocol the PCF8832 is a slave receiver/transmitter. if data is to be read from the device, the sdack pin must be connected, otherwise sdack may be unused. hs-mode can only commence after the following conditions: start condition (s) 8-bit master code (00001xxx) not-acknowledge bit (a). the master code has two functions, it allows arbitration and synchronization between competing masters at f/s-mode speeds, resulting in one winner. also the master code indicates the beginning of an hs-mode transfer. in figs 50 and 51 these conditions are visualized. as no device is allowed to acknowledge the master code, the master code is followed by a not-acknowledge ( a). after this a-bit, and the scl line has been pulled up to a high level, the active master switches to hs-mode and enables at t h the current-source pull-up circuit for the scl signal (see fig.51). the active master will then send a repeated start condition (sr) followed by a 7-bit slave address with a r/ w-bit and receives an acknowledge bit (a) from the selected slave. after each acknowledge bit (a) or not-acknowledge bit ( a), the active master disables its current-source pull-up circuit. the active master re-enables its current source again when all devices have released and the scl signal reaches a high level. the rising of the scl is done by a resistor pull-up and so is slower, the last part of the scl rise time is speeded up because the current source is enabled. data transfer only switches back to f/s-mode after a stop condition (p). a write sequence after the hs-mode is selected (see fig.53) is initiated with a start condition (s) from the i 2 c-bus master and this is followed by the slave address. all slaves with the corresponding address acknowledge in parallel, all the others will ignore the i 2 c-bus transfer. after acknowledgement of a write ( w) condition, one or more command words follow which define the status of the addressed slaves. a command word consists of a control byte, which defines co and d/ c, plus a data byte (see table 21, table 22 and fig.52). the last control byte is tagged with a cleared most significant bit, the continuation bit co. the control and data bytes are also acknowledged by all addressed slaves on the bus. table 21 de?nition of co table 22 de?nition of d/ c after the last control byte, depending on the d/ c bit setting, a series of display data bytes or command data bytes may follow. if the d/ c bit was set to logic 1, these display bytes are stored in the display ram at the address specified by the data pointer. the data pointer is updated automatically and the data is directed to the intended PCF8832. if the d/ c bit of the last control byte was set to 0, these command bytes will be decoded and the setting of the device will be changed according to the received commands. the acknowledgement after each byte is made only by the addressed PCF8832. at the end of the transmission the i 2 c-bus master issues a stop condition (p) and switches back to f/s-mode, however, to reduce the overhead of the master code, it is possible for a master to link a number of hs-mode transfers, separated by repeated start conditions (sr). a read sequence (fig.53) follows after the hs-mode is selected. the PCF8832 will immediately start to output the requested data until a not acknowledge is transmitted by the master. before the read access, the user has to set the d/ c bit to the appropriate value by a preceding write access. the write access should be terminated by a repeated start condition so that the hs-mode is not disabled. co action 0 last control byte to be sent; only a stream of data bytes are allowed to follow; this stream may only be terminated by a stop or re-start condition 1 another control byte will follow this control byte unless a stop or re-start condition is received d/ cr/ w action 0 0 command byte will be decoded and used to set up the device 1 command byte of requested adr will be returned 1 0 data byte will be stored in the display ram 1 ram read-back is not supported 2002 aug 16 49 philips semiconductors preliminary speci?cation stn rgb -
