Function description
Multifunction serial interface ch.2
input pin
Multifunction serial interface ch.2
output pin.
This pin operates as SOT2 when it is
used in a UART/CSIO/LIN
(operation modes 0 to 3) and as
SDA2 when it is used in an I²C
(operation mode 4).
Multifunction serial interface ch.2
clock I/O pin.
This pin operates as SCK2 when it is
used in a UART/CSIO (operation
modes 0 to 2) and as SCL2 when it is
used in an I²C (operation mode 4).
Multifunction serial interface ch.3
input pin
Multifunction serial interface ch.3
output pin.
This pin operates as SOT3 when it is
used in a UART/CSIO/LIN
(operation modes 0 to 3) and as
SDA3 when it is used in an I²C
(operation mode 4).
Multifunction serial interface ch.3
clock I/O pin.
This pin operates as SCK3 when it is
used in a UART/CSIO (operation
modes 0 to 2) and as SCL3 when it is
used in an I²C (operation mode 4).
Pin No.
