Port P general purpose input/output data—Data Register
Port P pin 3 is associated with the PWM output channel 3 and the SS signal of SPI1.
The PWM function takes precedence over the SPI1 and the general purpose I/O function if the PWM channel 3 is
enabled. The SPI1 function takes precedence of the general purpose I/O function if the routed SPI1 is enabled.
When not used with the alternative functions, these pins can be used as general purpose I/O.
If the associated data direction bits of these pins are set to 1, a read returns the value of the port register, otherwise
the buffered pin input state is read.
Port P general purpose input/output data—Data Register
Port P pin 2 is associated with the PWM output channel 2 and the SCK signal of SPI1.
The PWM function takes precedence over the SPI1 and the general purpose I/O function if the PWM channel 2 is
enabled. The SPI1 function takes precedence of the general purpose I/O function if the routed SPI1 is enabled.
When not used with the alternative functions, these pins can be used as general purpose I/O.
If the associated data direction bits of these pins are set to 1, a read returns the value of the port register, otherwise
the buffered pin input state is read.
Port P general purpose input/output data—Data Register
Port P pin 1 is associated with the PWM output channel 1 and the MOSI signal of SPI1.
The PWM function takes precedence over the SPI1 and the general purpose I/O function if the PWM channel 1 is
enabled. The SPI1 function takes precedence of the general purpose I/O function if the routed SPI1 is enabled.
When not used with the alternative functions, these pins can be used as general purpose I/O.
If the associated data direction bits of these pins are set to 1, a read returns the value of the port register, otherwise
the buffered pin input state is read.
Port P general purpose input/output data—Data Register
Port P pin 0 is associated with the PWM output channel 0 and the MISO signal of SPI1.
The PWM function takes precedence over the SPI1 and the general purpose I/O function if the PWM channel 0 is
enabled. The SPI1 function takes precedence of the general purpose I/O function if the routed SPI1 is enabled.
When not used with the alternative functions, these pins can be used as general purpose I/O.
If the associated data direction bits of these pins are set to 1, a read returns the value of the port register, otherwise
the buffered pin input state is read.
