FUNCTION DESCRIPTION
SYSTEM INTERFACE
S6A0093 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.

NOTES:
1. Don’t care (high, low or open)
2. Fixed high (V

)
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
