1.2.3.67
PP0 / KWP0 / PWM0 / MISO1 / TIMIOC0— Port P I/O Pin 0
PP0 is a general-purpose input or output pin. It can be congured as a keypad wakeup input. It can be
congured 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] — Port R I/O Pins [7:0]
PR[7:0] are general-purpose input or output pins. They can be congured as input capture or output
compare pins IOC[7:0] of the standard timer (TIM).
1.2.3.69
PS7 / SS0 — Port S I/O Pin 7
PS7 is a general-purpose input or output pin. It can be congured as the slave select pin SS of the serial
peripheral interface 0 (SPI0).
1.2.3.70
PS6 / SCK0 — Port S I/O Pin 6
PS6 is a general-purpose input or output pin. It can be congured as the serial clock pin SCK of the serial
peripheral interface 0 (SPI0).
1.2.3.71
PS5 / MOSI0 — Port S I/O Pin 5
PS5 is a general-purpose input or output pin. It can be congured 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 — Port S I/O Pin 4
PS4 is a general-purpose input or output pin. It can be congured 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 — Port S I/O Pin 3
PS3 is a general-purpose input or output pin. It can be congured as the transmit pin TXD of serial
communication interface 1 (SCI1).
1.2.3.74
PS2 / RXD1 — Port S I/O Pin 2
PS2 is a general-purpose input or output pin. It can be congured as the receive pin RXD of serial
communication interface 1 (SCI1).
1.2.3.75
PS1 / TXD0 — Port S I/O Pin 1
PS1 is a general-purpose input or output pin. It can be congured as the transmit pin TXD of serial
communication interface 0 (SCI0).
