S6A0092

FUNCTION DESCRIPTION

SYSTEM INTERFACE

S6A0092 has two kinds of interface type with MPU: bus mode, serial mode. Serial or bus mode is selected by PS pin.

In bus mode, 4-bit bus or 8-bit bus is selected by IF pin, and 68 series MPU or 80 series MPU is selected by MI pin.

SI

PS: "High" = bus mode, "Low" = serial mode

MI: "High" = 68-series MPU, "Low" = 80-series MPU

IF: "High" = 8 bit mode, "Low" = 4 bit mode (PS: "High")

CSB: "High" = chip is not selected, "Low" = chip is selected

RS: "High" = data register, "Low" = instruction register

RW_WR: Read / Write indicating signal in 68 mode or active low signal for enabling write in 80 mode

E_RD: Active high signal for enabling command is 68 mode or active low signal for enabling read in 80 mode.

SCL (DB6): Serial clock input

SI (DB7): Serial data input
