Chapter 1 Device Overview MC9S12XE-Family

1.2.3.67 PP0 / KWP0 / PWM0 / MISO1 / TIMIOC0â Port P I/O Pin 0

PP0 is a general-purpose input or output pin. It can be conï¬gured as a keypad wakeup input. It can be

conï¬gured as pulse width modulator (PWM) channel 0 output, TIM channel 0 or as the master input

(during master mode) or slave output (during slave mode) pin MISO of the serial peripheral interface 1

(SPI1).

1.2.3.68 PR[7:0] / TIMIOC[7:0] â Port R I/O Pins [7:0]

PR[7:0] are general-purpose input or output pins. They can be conï¬gured as input capture or output

compare pins IOC[7:0] of the standard timer (TIM).

1.2.3.69 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).

1.2.3.70 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).

1.2.3.71 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).

1.2.3.72 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).

1.2.3.73 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).

1.2.3.74 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).

1.2.3.75 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).
