CHAPTER 2 PIN FUNCTIONS
2.2.2 P10 to P17
P10 to P17 function as an I/O port. This port can also be used for external interrupt request input, serial interface data
I/O, clock I/O, and timer I/O.
Input to the P10, P11, P14, and P15 pins can be specified through a normal input buffer or a TTL input buffer in 1-bit
units using port input mode register 1 (PIM1).
Output from the P10-P15 pins can be specified as N-ch open-drain output (VDD tolerance) in 1-bit units using port
output mode register 1 (POM1).

The following operation modes can be specified in 1-bit units.
(1) Port mode
P10 to P17 function as an I/O port. P10 to P17 can be set to input or output port 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).
(2) Control mode
P10 to P17 function as serial interface clock I/O, data I/O, timer I/O, and external interrupt request input.
(a) SCK10, SCK20
These are serial clock I/O pin of serial interface CSI10 and CSI20.
(b) SI10, SI20
These are serial data input pin of serial interface CSI10 and CSI20.
(c) SO10, SO20
These are serial data output pin of serial interface CSI10 and CSI20.
(d) SCL10, SCL20
These are serial clock I/O pin of serial interface IIC10 and IIC20 (simplified I²C).
(e) SDA10, SDA20
These are serial data I/O pin of serial interface IIC10 and IIC20 (simplified I²C).
(f) RxD1, RxD2
These are serial data input pin of serial interface UART1 and UART2.
