P10 to P17 function as an 8-bit I/O port. These pins also function as pins for external interrupt request input, serial
The following operation modes can be specified in 1-bit units.
P10 to P17 function as an 8-bit I/O port. P10 to P17 can be set to input or output in 1-bit units using port mode
register 1 (PM1). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 1 (PU1).
P10 to P17 function as external interrupt request input, serial interface data I/O, clock I/O, timer I/O, and flash
memory programming mode setting.

(b) SO10
(c) SCK10
(d) RxD0, RxD6
(e) TxD0, TxD6
(f) TI50
(g) TO50, TOH0, and TOH1
(h) INTP5
(i)
This is a serial interface serial data input pin.
This is a serial interface serial data output pin.
This is a serial interface serial clock I/O pin.
These are the serial data input pins of the asynchronous serial interface.
These are the serial data output pins of the asynchronous serial interface.
This is the pin for inputting an external count clock to 8-bit timer/event counter 50.
These are timer output pins.
This is an external interrupt request input pin for which the valid edge (rising edge, falling edge, or both rising
and falling edges) can be specified.
FLMD1
This is the pin for setting the flash memory programming mode.
