4. Extended Serial I/O Interface
This block is a serial I/O interface implemented on a single 8-bit channel that can transfer data in synchronization
with clock pulses. It allows the “LSB first” or “MSB first” option to be selected for data transfer. The serial I/O
port to be used can also be selected.
There are two serial I/O operation modes available:
Internal shift clock mode: Transfers data in synchronization with internal clock pulses.
External shift clock mode: Transfers data in synchronization with clock pulses entered from an external pin
(SCKx). In this mode, data can be transferred by instructions from the CPU by
operating the general-purpose port that shares the external pin (SCKx).
