PH0 / KWH0 / MISO1 — Port H I/O Pin 0
PH0 is a general-purpose input or output pin. It can be congured to generate an interrupt causing the
MCU to exit stop or wait mode. It can be congured as master input (during master mode) or slave output
(during slave mode) pin MISO of the serial peripheral interface 1 (SPI1).
1.2.3.33
PJ7 / KWJ7 / TXCAN4 / SCL0 / TXCAN0— PORT J I/O Pin 7
PJ7 is a general-purpose input or output pin. It can be congured to generate an interrupt causing the MCU
to exit stop or wait mode. It can be congured as the transmit pin TXCAN for the scalable controller area
network controller 0 or 4 (CAN0 or CAN4) or as the serial clock pin SCL of the IIC0 module.
1.2.3.34
PJ6 / KWJ6 / RXCAN4 / SDA0 / RXCAN0 — PORT J I/O Pin 6
PJ6 is a general-purpose input or output pin. It can be congured to generate an interrupt causing the MCU
to exit stop or wait mode. It can be congured as the receive pin RXCAN for the scalable controller area
network controller 0 or 4 (CAN0 or CAN4) or as the serial data pin SDA of the IIC0 module.
1.2.3.35
PJ5 / KWJ5 / SCL1 / CS2 — PORT J I/O Pin 5
PJ5 is a general-purpose input or output pin. It can be congured to generate an interrupt causing the MCU
to exit stop or wait mode. It can be congured as the serial clock pin SCL of the IIC1 module. It can be
congured to provide a chip-select output.
1.2.3.36
PJ4 / KWJ4 / SDA1 / CS0 — PORT J I/O Pin 4
PJ4 is a general-purpose input or output pin. It can be congured to generate an interrupt causing the MCU
to exit stop or wait mode. It can be congured as the serial data pin SDA of the IIC1 module. It can be
congured to provide a chip-select output.
1.2.3.37
PJ2 / KWJ2 / CS1 — PORT J I/O Pin 2
PJ2 is a general-purpose input or output pins. It can be congured to generate an interrupt causing the
MCU to exit stop or wait mode. It can be congured to provide a chip-select output.
1.2.3.38
PJ1 / KWJ1 / TXD2 — PORT J I/O Pin 1
PJ1 is a general-purpose input or output pin. It can be congured to generate an interrupt causing the MCU
to exit stop or wait mode. It can be congured as the transmit pin TXD of the serial communication
interface 2 (SCI2).
1.2.3.39
PJ0 / KWJ0 / RXD2 / CS3 — PORT J I/O Pin 0
PJ0 is a general-purpose input or output pin. It can be congured to generate an interrupt causing the MCU
to exit stop or wait mode. It can be congured as the receive pin RXD of the serial communication interface
2 (SCI2).It can be congured to provide a chip-select output.
