Function
6
P27
G
(CMOS)
General-purpose I/O port
At this pin, a pull-up resistor is added in the input mode depending
on the settings of the pull-up resistor setting register.
CKOT
Clock output pin
This function is available when clock output is enabled.
7
P30
E
(CMOS/H)
General-purpose I/O port
SIN1
I/O extended serial data input pin
This pin, as required, is used for input during input operation, and it
is necessary to disable output for other functions from this pin
unless such output is made intentionally.
8
P31
D
(CMOS)
General-purpose I/O port
SOT1
I/O extended serial data output pin
This function is available when serial data data output is enabled.
9
V
SS
Power supply
Digital circuit power supply (GND) pin
10
P32
E
(CMOS/H)
General-purpose I/O port
SCK1
I/O extended serial clock I/O pins
This function is available when clock input is enabled.
This pin, as required, is used for input during input operation, and it
is necessary to disable output for other functions from this pin
unless such output is made intentionally.
11 to 14
P33 to P36
D
(CMOS)
General-purpose I/O ports
15
P37
E
(CMOS/H)
General-purpose I/O port
TRG
PPG0 and PPG1 external trigger input pin
ATG
A/D converter trigger input pin
During A/D converter input operations, these inputs may be used at
any time; therefore, it is necessary to stop output by other functions
on these pins, except when using them for output deliberately.
16
P40
D
(CMOS)
General-purpose I/O port
This function is available when PPG timer 0 output is disabled.
PPG0
PPG timer 0 output pin
This function is available when the PPG timer 0 waveform output is
enabled.
17
P41
D
(CMOS)
General-purpose I/O port
This function is available when PPG timer 1 output is disabled.
PPG1
PPG timer 1 output pin
This function is available when the PPG timer 1 waveform output is
enabled.
