2.3.36 PM3 / TXCAN1 / TXCAN0 / SS0 — Port M I/O Pin 3
PM3 is a general purpose input or output pin. It can be configured as the transmit pin TXCAN of the
Motorola Scalable Controller Area Network controllers 1 or 0 (CAN1 or CAN0). It can be configured as
the slave select pin SS of the Serial Peripheral Interface 0 (SPI0).
2.3.37 PM2 / RXCAN1 / RXCAN0 / MISO0 — Port M I/O Pin 2
PM2 is a general purpose input or output pin. It can be configured as the receive pin RXCAN of the
Motorola Scalable Controller Area Network controllers 1 or 0 (CAN1 or CAN0). It can be configured as
the master input (during master mode) or slave output pin (during slave mode) MISO for the Serial
Peripheral Interface 0 (SPI0).
2.3.38 PM1 / TXCAN0 — Port M I/O Pin 1
PM1 is a general purpose input or output pin. It can be configured as the transmit pin TXCAN of the
Motorola Scalable Controller Area Network controller 0 (CAN0).
2.3.39 PM0 / RXCAN0 — Port M I/O Pin 0
PM0 is a general purpose input or output pin. It can be configured as the receive pin RXCAN of the
Motorola Scalable Controller Area Network controller 0 (CAN0).
2.3.40 PP7 / KWP7 / PWM7 / SCK2 — Port P I/O Pin 7
PP7 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 Pulse Width Modulator (PWM) channel 7 output. It
can be configured as serial clock pin SCK of the Serial Peripheral Interface 2 (SPI2).
2.3.41 PP6 / KWP6 / PWM6 / SS2 — Port P I/O Pin 6
PP6 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 Pulse Width Modulator (PWM) channel 6 output. It
can be configured as slave select pin SS of the Serial Peripheral Interface 2 (SPI2).
2.3.42 PP5 / KWP5 / PWM5 / MOSI2 — Port P I/O Pin 5
PP5 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 Pulse Width Modulator (PWM) channel 5 output. It
can be configured as master output (during master mode) or slave input pin (during slave mode) MOSI of
the Serial Peripheral Interface 2 (SPI2).
