Port 10
Port 10 is an 8-bit I/O port for which I/O settings can be controlled in 1-bit units.
Pull-up resistors can be connected in 1-bit units (software pull-up function).
When using P100 to P107 as the KR0 to KR7 pins, noise is eliminated by an analog noise eliminator.
After reset:

Remark
In input mode:
When P10 is read, the pin levels at that time are read. Writing to P10 writes the
values to that port. This does not affect the input pins.
In output mode: When P10 is read, the values of P10 are read. Writing to P10 writes the values to
that port, and those values are immediately output.
Port 10 includes the following alternate functions.
