Port P general purpose input/output data—Data Register
Port P pin 6 is associated with the PWM output channel 7 and the SCK signal of SPI2.
The PWM function takes precedence over the SPI2 and the general purpose I/O function if the PWM channel 7 is
enabled. The SPI2 function takes precedence of the general purpose I/O function if the routed SPI2 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 6 is associated with the PWM output channel 6 and the SS signal of SPI2.
The PWM function takes precedence over the SPI2 and the general purpose I/O function if the PWM channel 6 is
enabled. The SPI2 function takes precedence of the general purpose I/O function if the routed SPI2 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 5 is associated with the PWM output channel 5 and the MOSI signal of SPI2.
The PWM function takes precedence over the SPI2 and the general purpose I/O function if the PWM channel 5 is
enabled. The SPI2 function takes precedence of the general purpose I/O function if the routed SPI2 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 4 is associated with the PWM output channel 4 and the MISO signal of SPI2.
The PWM function takes precedence over the SPI2 and the general purpose I/O function if the PWM channel 4 is
enabled. The SPI2 function takes precedence of the general purpose I/O function if the routed SPI2 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.
