CHAPTER 2 PIN FUNCTIONS
2.2.9 P80 to P87
P80 to P87 function as an I/O port. This port can also be used for serial interface clock I/O, data I/O, timer I/O, and
external interrupt request input.
Output from the P80 and P82 pins can be specified as N-ch open-drain output (VDD tolerance) in 1-bit units using port
output mode register 8 (POM8).

The following operation modes can be specified in 1-bit units.
(1) Port mode
P80 to P87 function as an I/O port. P80 to P87 can be set to input or output port in 1-bit units using port mode
register 8 (PM8). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 8 (PU8).
(2) Control mode
P80 to P87 function as serial interface clock I/O, data I/O, timer I/O, and external interrupt request input.
(a) SCK00
This is a clock I/O pin of serial interface CSI00.
(b) SI00
This is a serial data input pin of serial interface CSI00.
(c) SO00
This is a serial data output pin of serial interface CSI00.
(d) RxD0
This is a serial data input pin for serial interface UART0.
(e) TxD0
This is a serial data output pin for serial interface UART0.
(f) TI10 to TI13
These are the timer input pins of 16-bit timers 10 to 13.
(g) TO10 to TO13
These are the timer output pins of 16-bit timers 10 to 13.
