2.3.43 PP4 / KWP4 / PWM4 / MISO2 — Port P I/O Pin 4

PP4 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 4 output. It

can be configured as master input (during master mode) or slave output (during slave mode) pin MISO of

the Serial Peripheral Interface 2 (SPI2).

2.3.44 PP3 / KWP3 / PWM3 / SS1 — Port P I/O Pin 3

PP3 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 3 output. It

can be configured as slave select pin SS of the Serial Peripheral Interface 1 (SPI1).

2.3.45 PP2 / KWP2 / PWM2 / SCK1 — Port P I/O Pin 2

PP2 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 2 output. It

can be configured as serial clock pin SCK of the Serial Peripheral Interface 1 (SPI1).

2.3.46 PP1 / KWP1 / PWM1 / MOSI1 — Port P I/O Pin 1

PP1 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 1 output. It

can be configured as master output (during master mode) or slave input pin (during slave mode) MOSI of

the Serial Peripheral Interface 1 (SPI1).

2.3.47 PP0 / KWP0 / PWM0 / MISO1 — Port P I/O Pin 0

PP0 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 0 output. 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).

2.3.48 PS7 / SS0 — Port S I/O Pin 7

PS6 is a general purpose input or output pin. It can be configured as the slave select pin SS of the Serial

Peripheral Interface 0 (SPI0).

2.3.49 PS6 / SCK0 — Port S I/O Pin 6

PS6 is a general purpose input or output pin. It can be configured as the serial clock pin SCK of the Serial

Peripheral Interface 0 (SPI0).
