Chapter 1 Device Overview (MC3S12RG128V1)

1.2.3.47 PP1 / KWP1 / PWM1 / MOSI1 â Port P I/O Pin 1

PP1 is a general purpose input or output pin. It can be conï¬gured to generate an interrupt causing the MCU

to exit STOP or WAIT mode. It can be conï¬gured as Pulse Width Modulator (PWM) channel 1 output. It

can be conï¬gured as master output (during master mode) or slave input pin (during slave mode) MOSI of

the Serial Peripheral Interface 1 (SPI1).

1.2.3.48 PP0 / KWP0 / PWM0 / MISO1 â Port P I/O Pin 0

PP0 is a general purpose input or output pin. It can be conï¬gured to generate an interrupt causing the MCU

to exit STOP or WAIT mode. It can be conï¬gured as Pulse Width Modulator (PWM) channel 0 output. It

can be conï¬gured as master input (during master mode) or slave output (during slave mode) pin MISO of

the Serial Peripheral Interface 1 (SPI1).

1.2.3.49 PS7 / SS0 â Port S I/O Pin 7

PS7 is a general purpose input or output pin. It can be conï¬gured as the slave select pin SS of the Serial

Peripheral Interface 0 (SPI0).

1.2.3.50 PS6 / SCK0 â Port S I/O Pin 6

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

Peripheral Interface 0 (SPI0).

1.2.3.51 PS5 / MOSI0 â Port S I/O Pin 5

PS5 is a general purpose input or output pin. It can be conï¬gured as master output (during master mode)

or slave input pin (during slave mode) MOSI of the Serial Peripheral Interface 0 (SPI0).

1.2.3.52 PS4 / MISO0 â Port S I/O Pin 4

PS4 is a general purpose input or output pin. It can be conï¬gured as master input (during master mode) or

slave output pin (during slave mode) MOSI of the Serial Peripheral Interface 0 (SPI0).

1.2.3.53 PS3 / TXD1 â Port S I/O Pin 3

PS3 is a general purpose input or output pin. It can be conï¬gured as the transmit pin TXD of Serial

Communication Interface 1 (SCI1).

1.2.3.54 PS2 / RXD1 â Port S I/O Pin 2

PS2 is a general purpose input or output pin. It can be conï¬gured as the receive pin RXD of Serial

Communication Interface 1 (SCI1).

1.2.3.55 PS1 / TXD0 â Port S I/O Pin 1

PS1 is a general purpose input or output pin. It can be conï¬gured as the transmit pin TXD of Serial

Communication Interface 0 (SCI0).
