Interface with MPU in Serial Mode (PS = "Low")
When PS input pin is "Low", clock synchronized serial interface mode is selected. At this time, four ports, SCL
(DB6, synchronizing transfer clock), SI (DB7, serial input data), RS (register selection input) and CSB (chip
selection input) are used.
By setting CSB to "Low", S6A0094 can receive SCL input. If CSB is set to "High", S6A0094 resets the internal 8-
bit shift register and 3-bit counter. Serial data is input in the order of "D7, D6, D5, D4, D3, D2, D1, D0" from the
serial data input pin (SI = DB7) at the rising edge of serial clock (SCL = DB6).
At the rising edge of the 8th serial clock, the serial data (D7-D0) is converted into 8 bit bus mode data. The RS
input of the DR/IR selection is latched at the rising edge of the 8th serial clock (SCL).
In serial mode, the read is not possible.
