CHAPTER 2 PIN FUNCTIONS
(g) TxD1, TxD2
These are serial data output pin of serial interface UART1 and UART2.
(h) TI05
This is a timer input pin of 16-bit timer 05.
(i) TO02, TO04, TO05
These are the timer output pins of 16-bit timers 02, 04, and 05.
(j) INTP4, INTP6, INTP7, INTP10
These are the external interrupt request input pins for which the valid edge (rising edge, falling edge, or both
rising and falling edges) can be specified.

To use P10/SCK20/SCL20 and P11/SI20/RxD2/SDA20/INTP6 as a general-purpose port, note the
serial array unit 1 setting. For details, refer to Table 14-9 Relationship Between Register Settings
and Pins (Channel 0 of unit 1: CSI20, UART2 Reception, IIC20).
To use P12/TO02/SO20/TxD2 as a general-purpose port, set bit 2 (TO02) of timer output register 0
(TO0) and bit 2 (TOE02) of timer output enable register 0 (TOE0) to “0”, which is the same as
their default status setting. And as a general-purpose port, note the serial array unit 1 setting.
For details of serial array unit 1 setting, refer to Table 14-9 Relationship Between Register
Settings and Pins (Channel 0 of unit 1: CSI20, UART2 Reception, IIC20).
To use P13/TO04/SO10/TxD1 as a general-purpose port, set bit 4 (TO04) of timer output register 0
(TO0) and bit 4 (TOE04) of timer output enable register 0 (TOE0) to “0”, which is the same as
their default status setting. And as a general-purpose port, note the serial array unit 0 setting.
For details of serial array unit 0 setting, refer to Table 14-7 Relationship Between Register
Settings and Pins (Channel 2 of unit 0: CSI10, UART1 Transmission, IIC10)
To use P14/SI10/RxD1/SDA10/INTP4 and P15/SCK10/SCL10/INTP7 as a general-purpose port,
note the serial array unit 0 setting. For details, refer to Table 14-7 Relationship Between Register
Settings and Pins (Channel 2 of unit 0: CSI10, UART1 Transmission, IIC10)
To use P16/TO05/TI05/INTP10 as a general-purpose port, set bit 5 (TO05) of timer output register
0 (TO0) and bit 5 (TOE05) of timer output enable register 0 (TOE0) to “0”, which is the same as
their default status setting.
