Extended I/O serial interface
The extended I/O serial interface transfers data using a clock synchronization system having an 8-bit x 1 channel
configuration.
For data transfer, you can select LSB first/MSB first.
(1) Register Configuration
Serial mode control upper status register 0 to 2 (SMCSH0 to SMCSH2)
Serial mode control lower status register 0 to 2 (SMCSL0 to SMCSL2)
Serial data register 0 to 2 (SDR0 to SDR2)
