Table 1-3-6 Pin Function Summary (4/6)

Name	No.	I/O	Function	Other Function	Description
RXD0A	19	Input	UART reception	SBI0A, P04	In the serial interface in UART mode, these pins
RXD0B	49		data input pin	SBI0B, P71	are configured as the received data input pin.
					Pull-up resistors can be selected by the P0PLU
RXD1A	16			SBI1A, P01
					register and P7PLUD register. Set this pin to the
				SDA4A	input mode by the P0DIR register and the P7DIR
RXD1B	46			SBI1B, P74	register, and to the serial input mode by the serial
					interface1 mode register 1 ( SC0MD1, SC1MD1).
					This can be used as normal I/O pin when the
					serial interface is not used.
TCO0A	22	I/O	Timer I/O pins	P10, RMOUT	Event counter clock input pins, overflow pulse
					and PWM signal output pins for 8-bit timers 0 , 1,
TCI00B	23			P11
					4, 5. To use these pins as event clock inputs,
TCI01	51			P12
					configure them as inputs by the P1DIR and
TCO4A	24			P13	P7DIR register. When the pins are used as
TCI04B	25			P37	inputs, pull-up resistors can be specified by the
					P1PLU, P7PLUD register. For overflow pulse,
TCI05	52			P77
					PWM signal output, select the special function pin
					by the port 1 output mode register (P1OMD) and
					set to the output mode by the P1DIR register.
					When not used for timer I/O, these can be used
					as normal I/O pins.
SDA4A	16	I/O	Serial interface	P01, SBI1A	Reception data input pins for serial interfaces 4.
			data I/O pins		During data communications, select n-channel
				RXD1A
					open-drain to comply with IIC communication
SDA4B	35			P53
					standard. Pull-up resistors can be selected by
					the P0PLU register and the P5PLU register.
					During data communications, select output mode
					by the P0DIR register and the P5DIR register.
					These can be used as normal I/O pins when the
					serial interface is not used.
SCL4A	17	I/O	Serial interface 4	P02, SBT1A,	Clock I/O pins for serial interfaces 4. During data
			clock I/O pins		communications, select n-channel open-drain to
					comply with IIC communication standard. Pull-up
					resistors can be selected by the P0PLU resister
					and the P5PLU register. During data
					communications, select output mode by the
					P0DIR register and the P5DIR register. These
					can be used as normal I/O pins when the serial
SCL4B	36			P54	interface is not used.
RMOUT	22	I/O	Remote control	P10,TCO0A	Output pin for remote control transmission signal
			transmission		with a carrier signal. For remote control carrier
			signal output pin		output, select the special function pin by the port
					1 output mode register (P1OMD) and set to the
					output mode by the P1DIR register. Also, set to
					the remote control carrier output by the remote
					control carrier output control register (RMCTR).
					This can be used as a normal I/O pin when
					remote control is not used.
