FUNCTION DESCRIPTION
System Interface This chip three kinds interface type with serial, 4-bit 8-bit bus. Serial bus(4-bit/8-bit) selected input, 4-bit 8-bit selected instruction register. During read write operation, 8-bit registers used. data register (DR), other instruction register(IR). data register(DR) used temporary data storage place being written into read from DDRAM/CGRAM/SEGRAM, target selected address setting instruction. Each internal operation, reading from writing into RAM, done automatically. Hence, after reads data, data next DDRAM/CGRAM/SEGRAM address transferred into automatically. Also after writes data data transferred into DDRAM/CGRAM/SEGRAM automatically. Instruction register(IR) used only store instruction code transferred from MPU. cannot read instruction data. select register, RS/CS input 4-bit/8-bit mode(IM "High") serial mode(IM "Low").

Read Busy Flag Address
This instruction shows whether KS0075 internal operation not. resultant High, means internal operation progress should wait until become "Low". Which then next instruction performed. this instruction value address counter also read.
Write data
Write binary 8-bit data DDRAM/CGRAM/SEGRAM. selection from DDRAM, CGRAM, SEGRAM, previous address instruction DDRAM address set, CGRAM address set, SEGRAM address set. instruction also determines direction RAM. After write operation, address automatically increased/decreased according entry mode.
Read data from
Read binary 8-bit data from DDRAM/CGRAM/SEGRAM. selection previous address instruction. address instruction performed before this instruction, data that read first invalid, direction determined. data read sever times without address instruction before read operation, correct data from second, first data would incorrect, there time margin transfer data. case DDRAM read operation, cursor shift instruction plays same role DDRAM address instruction also transfer data output data register. After read operation address counter automatically increased/decreased according entry mode. After CGRAM/SEGRAM read operation, display shift executed correctly. case write operation, increased/decreased like read operation after this. this time, indicates next address position, previous data only read read instruction.

INTERFACE WITH
KS0075 transfer data mode (4-bit 8-bit) serial mode with MPU. Hence, both types 8-bit used. case 4-bit mode, data transfer performed twice transfer byte data. When interfacing data length 4-bit, only ports, from DB7, used data bus. first higher 4-bit case 8-bit mode, contents DB7) transferred, then lower 4-bit case 8-bit mode, contents DB3) transferred. transfer performed twice. Busy Flag outputs "High" after second transfer ended. When interfacing data length 8-bit, transfer performed time through ports, from DB7. "Low", serial transfer mode set.

Interface with Serial Mode When port input "Low", serial interface mode started. this time, three ports, SCLK (synchronizing transfer clock), (serial input data), (serial output data), used. KS0075 used with other chips, chip select port (cs) used. setting "Low", KS0075 receive SCLK input. "High", KS0075 reset internal transfer counter. Before transfer real data, start byte transferred. composed succeeding "High" bits, read write control (R/W), register selection (RS), that indicates start byte. Whenever succeeding "High" bits detected KS0075, resets serial transfer counter prepares receive next information. next input data register selection which determine which register used, read write control that determine direction data. Then transferred, which must have "Low" value show start byte. (Refer Write Operation (R/W After start byte transferred from KS0075, 8-bit data transferred which divided into bytes, each byte bit's real data bit's partition token data. example, real data "10110001" D7), then serially transferred data becomes "1011 0000 0001 0000" where bits must "0000" safe transfer. transfer several bytes continuously without changing bit, start byte transfer needed only first starting time. I.e., after first start byte transferred, real data succeeding transferred. Read Operation (R/W After start byte transferred KS0075, receive 8-bit data through port time from LSB. Wait time needed insert between start byte data reading, internal reading from requires some delay. Continuous data reading possible such serial write operation. also needs only start bytes, only some delay between reading operations each byte inserted. During reading operation, KS0075 observes succeeding "High" from MPU. detected, KS0075 restarts serial operation once prepares receive bit. continuous reading operation, port must "Low".
