P30 To P35 (Port 3) - Renesas RL78/G1P Hardware User Manual

RL78/G1P
(a) ANI0 to ANI7
These are the analog input pins (ANI0 to ANI7) of A/D converter. See 9.10 (5) Analog input (ANIn) pins.
(b) AV
REFP
This is a pin that inputs the A/D converter reference potential (+ side).
(c) AV
REFM
This is a pin that inputs the A/D converter reference potential (side).
(d) ANO0, ANO1
These are the D/A converter output pins.

2.3.3 P30 to P35 (port 3)

P30 to P35 function as an I/O port. These pins also function as external interrupt request input, serial interface data I/O,
cock I/O, chip select input, programming UART I/O, and timer I/O.
Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 3 (PU3).
The following operation modes can be specified in 1-bit units.
(1) Port mode
P30 to P35 function as an I/O port. P30 and P31 can be set to input or output port in 1-bit units using port mode
register 3 (PM3).
(2) Control mode
P30 to P35 unction as external interrupt request input, serial interface data I/O, clock I/O, chip select input,
programming UART I/O, and timer I/O.
(a) INTP1, INTP2, INTP3
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.
(b) TxD0
This is a serial data output pin of serial data interface UART0.
(c) RxD0
This is a serial data input pin of serial data interface UART0.
(d) SI00
This is a serial data input pin of serial interface CSI00.
(e) SO00
This is a serial data output pin of serial interface CSI00.
(f) SCK00
This is a serial clock I/O pin of serial interface CSI00.
(g) SSI00
This is a chip select input pin of serial interface CSI00.
