Note:
When the serial interface function is working, the serial input-only pin (SI) can be used as an I/O port.
To use it as the SI pin, you need to set the I/O port to input.
Note:
All the serial interface pins are Schmitt input.
Note:
When the serial interface function is used and the I/O port input is enabled to break, the wait or clock
stop instruction will be released due to changes in serial input. Note that this requires input setting from
the I/O port control and reading of the I/O port input before execution of the instruction. When the clock
stop is released, CPU execution will be started after 100 ms of standby.
Note:
When the serial interface function is used, I/O port 3 can be set to a pull-up/pull-down state.
