Pin function
The pin function is switched as shown below according to the combination of the OEA bit in
DACR of the PWMX and the P84DDR bit.
The pin function is switched as shown below according to the combination of the RE bit in
SCR of the SCI_4, the ICE bit in ICCRA of the IIC3_1, and the P83DDR bit. When this pin is
used as the P83 output pin, the output format is NMOS push-pull output. The output format for
SDA1 is NMOS open-drain output, and direct bus drive is possible.
The pin function is switched as shown below according to the combination of the TE bit in
SCR of the SCI_4, the ICE bit in ICCRA of the IIC3_1, and the P82DDR bit. When this pin is
used as the TxD4 or P82 output pin, the output format is NMOS push-pull output. The output
format for SCL1 is NMOS open-drain output, and direct bus drive is possible.
