CHAPTER 2 PIN FUNCTIONS
(2) Control mode
P50 to P57 function as serial interface data I/O, timer input, and segment output of LCD controller/driver.
(a) RxD3
This is a serial data input pin of serial interface UART3.
(b) TxD3
This is a serial data output pin of serial interface UART3.
(c) TI02, TI04
These are the timer input pins of 16-bit timers 02 and 04.
(d) SEGxx
This is a segment output pin of LCD controller/driver.
2.2.7 P60, P61
P60 and P61 function as an I/O port. This port can also be used for s serial interface IICA data I/O and clock I/O.

The following operation modes can be specified in 1-bit units.
(1) Port mode
P60 and P61 function as an I/O port. P60 and P61 can be set to input port or output port in 1-bit units using port
mode register 6 (PM6).
Output of P60 and P61 is N-ch open-drain output (6 V tolerance).
(2) Control mode
P60 and P61 function as serial interface IICA clock I/O and data I/O.
(a) SCL0
This is a serial clock I/O pin of serial interface IICA.
(b) SDA0
This is a serial data I/O pin of serial interface IICA.
Caution When using P60/SCL0 and P61/SDA0 as a general-purpose port, stop the operation of serial
interface IICA.
