14.2.9 Port 10
connected in 1-bit units (software pull-up function).
Port 10
Port 10 is an 8-bit I/O port for which I/O settings can be controlled in 1-bit units. A pull-up resistor can be
The pins in this port are selectable as normal outputs or N-ch open-drain outputs.

When port 10 (P10) is read, the pin levels at that time are read. Writing to P10
writes the values to that register. This does not affect the input pins.
When port 10 (P10) is read, the P10 values are read. Writing to P10
writes the values to that register, and those values are immediately output.
