Output compare output

These pins are available as ports when output compare output is not al-

lowed.

PF0/IN0

PF1/IN1

PF2/IN2

PF3/IN3

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.

PF4

General purpose I/O port

PG0/PPG0

PG1/PPG1

PG2/PPG2

PG3/PPG3

PG4/PPG4

PG5/PPG5

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.

PJ1/SDA

I2C interface I/O pin

This function is enabled when the I2C interface is allowed to operate.

While the I2C interface is in operation, keep the port output set to Hi-Z.

This pin is available as a port when the I2C interface is not in use.

100

PJ0/SCL

I2C interface I/O pin

This function is enabled when the I2C interface is allowed to operate.

While the I2C interface is in operation, keep the port output set to Hi-Z.

This pin is available as a port when the I2C interface is not in use.

102

PI5/SCK3/TO3

UART3 clock I/O, Reload timer 3 output

When UART3 clock output is not allowed, reload timer 3 can be output by

allowing it.

This pin is available as a port when neither UART3 clock output nor reload

timer output is allowed.

103

PI4/SOT3

UART3 data output

This function is enabled when UART3 data output is allowed.

This pin is available as a port when UART3 clock output is not allowed.

104

PI3/SIN3

UART3 data input

Since this input is used more or less continuously while UART3 is en-

gaged in input operations, output by the port needs to be stopped except

when it is performed deliberately.

This pin is available as a port when UART3 output data input is not in use.
