PF0/IN0
PF1/IN1
PF2/IN2
PF3/IN3
F
Input capture input
This function is enabled when the input capture operation is input.
These pins are available as ports when input capture input is not in use.
90
PF4
F
General purpose I/O port
91

PG0/PPG0
PG1/PPG1
PG2/PPG2
PG3/PPG3
F
PPG timer output
This function is enabled when PPG timer output is allowed.
These pins are available as ports when PPG timer output is not allowed.
97
PI2/SCK2/TO2
P
UART2 clock I/O, Reload timer 2 output
When UART2 clock output is not allowed, reload timer 2 can be output by
allowing it.
This pin is available as a port when neither UART2 clock output nor reload
timer output is allowed.
98
PI1/SOT2
P
UART2 data output
This function is enabled when UART2 data output is allowed.
This pin is available as a port when UART2 clock output is not allowed.
99
PI0/SIN2
P
UART2 data input
Since this input is used more or less continuously while UART2 is
engaged in input operations, output by the port needs to be stopped
except when it is performed intentionally.
This pin is available as a port when UART2 data input is not in use.
100
PH2/SCK0/TO0
P
UART0 clock I/O, Reload timer 0 output
When UART0 clock output is not allowed, reload timer 0 can be output by
allowing it.
This pin is available as a port when neither UART0 clock output nor reload
timer output is allowed.
101
PH1/SOT0
P
UART0 data output
This function is enabled when UART0 data output is allowed.
This pin is available as a port when UART0 clock output is not allowed.
102
PH0/SIN0
P
UART0 data input
Since this input is used more or less continuously while UART0 is
engaged in input operations, output by the port needs to be stopped
except when it is performed intentionally.
This pin is available as a port when UART0 data input is not in use.
103
SSEL
G
Sector mode switching pin of FLASH
This pin should be connected to VCC or VSS.
104
105
106
DA2
DA1
DA0
D/A converter output
This function is enabled when D/A converter output is allowed.
107
DAVS
Power supply pin for D/A converter
108
DAVC
Power supply pin for D/A converter
109
AVCC
VCC power supply pin for A/D converter
