FUNCTION DESCRIPTION
divided into serial data input (SDA, SCL). Parallel or serial selection is decided by P/S pin setting.
Reading out from internal register or RAM is not possible at serial interface mode.
8bit/16bit MPU through data bus. SEL68 port setting makes 80-series or 68-series interface
selection
HM17CM256 receives data through 8 bit parallel I/O(D
P/S
Parallel or serial selection is possible as following table.
