Port A general purpose input/output data—Data Register
If the associated data direction bit of this pin is set to 1, a read returns the value of the port register, otherwise the buffered and
synchronized pin input state is read.
Port A general purpose input/output data—Data Register
If the associated data direction bit of this pin is set to 1, a read returns the value of the port register, otherwise the buffered and
synchronized pin input state is read.
Port A general purpose input/output data—Data Register
Port A pin 3 is associated with the SS signal of the SPI module.
When not used with the alternative function, this pin can be used as general purpose I/O.
If the associated data direction bit of this pin is set to 1, a read returns the value of the port register, otherwise the buffered and
synchronized pin input state is read.
Port A general purpose input/output data—Data Register
Port A pin 2 is associated with the SCK signal of the SPI module.
When not used with the alternative function, this pin can be used as general purpose I/O.
If the associated data direction bit of this pin is set to 1, a read returns the value of the port register, otherwise the buffered and
synchronized pin input state is read.
Port A general purpose input/output data—Data Register
Port A pin 1 is associated with the MOSI signal of the SPI module.
When not used with the alternative function, this pin can be used as general purpose I/O.
If the associated data direction bit of this pin is set to 1, a read returns the value of the port register, otherwise the buffered and
synchronized pin input state is read.
Port A general purpose input/output data—Data Register
Port A pin 0 is associated with the MISO signal of the SPI module.
When not used with the alternative function, this pin can be used as general purpose I/O.
If the associated data direction bit of this pin is set to 1, a read returns the value of the port register, otherwise the buffered and
synchronized pin input state is read.
