When parallel interface is selected (P/S=”H”), data line is
connected to MPU data bus with 8bit bi-directional bus
When serial interface is selected (P/S=”L”),
D
and D
(SCL, SDA) are used as serial interface pins and
various sets are taken by serial interface use mode of D

SDA : serial data input pin
SCL : data transfer clock
EXCS : extension chip selection I/O pin
SMODE : serial transfer mode setting input pin
SPOL : RS polarity selection pin when 3 line serial interface is
selected.
SDA data is shifted at the rising edge of SCL
Internal serial/parallel conversion into 8-bit data occurs at the rising
edge of 8
