9, 10
P40, P41
D
General-purpose I/O ports
Only available when waveform outputs from PG10 and PG11 are disabled.
The settings in the pull-up resistor setup register (RDR4) are enabled
when ports are set as inputs. The RDR4 settings are ignored when ports
are set as outputs.
PG10,
PG11
Output pins for 8/16-bit PPG timer 1
Only available when waveform output is enabled for PG10 and PG11.
11
P42
D
General-purpose I/O port
The settings in the pull-up resistor setup register (RDR4) are enabled
when ports are set as inputs. The RDR4 settings are ignored when ports
are set as outputs.
SIN0
UART (SCI) serial data input pin
Input operates continuously when the UART is performing input.
Accordingly, output to the pin from other functions that share this pin must
be suspended unless performed intentionally.
12
P43
D
General-purpose I/O port
The settings in the pull-up resistor setup register (RDR4) are enabled
when ports are set as inputs. The RDR4 settings are ignored when ports
are set as outputs.
SOT0
UART (SCI) serial data output pin
Only available when serial data output is enabled for the UART (SCI) .
13
P44
D
General-purpose I/O port
The settings in the pull-up resistor setup register (RDR4) are enabled
when ports are set as inputs. The RDR4 settings are ignored when ports
are set as outputs.
SCK0
UART (SCI) serial clock input/output pin
Only available when serial clock output is enabled for the UART (SCI) .
14
P45
D
General-purpose I/O port
The settings in the pull-up resistor setup register (RDR4) are enabled
when ports set as inputs. The RDR4 settings are ignored when ports set
are as outputs.
SIN1
Data input pin for extended I/O serial interface 1
Input operates continuously when the performing serial input. Accordingly,
output to the pin from other functions that share this pin must be
suspended unless performed intentionally.
15
P46
D
General-purpose I/O port
The settings in the pull-up resistor setup register (RDR4) are enabled
when ports set as inputs. The RDR4 settings are ignored when ports are
set as outputs.
SOT1
Data output pin for extended I/O serial interface 1
Only available when serial data output is enabled for SOT1.
