1.2.3.32

PH0 / KWH0 / MISO1 — Port H I/O Pin 0

PH0 is a general-purpose input or output pin. It can be conﬁgured to generate an interrupt causing the

MCU to exit stop or wait mode. It can be conﬁgured 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 conﬁgured to generate an interrupt causing the MCU

to exit stop or wait mode. It can be conﬁgured 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 conﬁgured to generate an interrupt causing the MCU

to exit stop or wait mode. It can be conﬁgured 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 conﬁgured to generate an interrupt causing the MCU

to exit stop or wait mode. It can be conﬁgured as the serial clock pin SCL of the IIC1 module. It can be

conﬁgured 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 conﬁgured to generate an interrupt causing the MCU

to exit stop or wait mode. It can be conﬁgured as the serial data pin SDA of the IIC1 module. It can be

conﬁgured 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 conﬁgured to generate an interrupt causing the

MCU to exit stop or wait mode. It can be conﬁgured 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 conﬁgured to generate an interrupt causing the MCU

to exit stop or wait mode. It can be conﬁgured 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 conﬁgured to generate an interrupt causing the MCU

to exit stop or wait mode. It can be conﬁgured as the receive pin RXD of the serial communication interface

2 (SCI2).It can be conﬁgured to provide a chip-select output.
