26.3.2.3 Port Pin Data/Set Data Registers (PORTnP/SETn)
The PORTnP/SETn registers reflect the current pin states and control the setting of output pins when the
pin is configured for digital I/O.
Most PORTn registers have a full 8-bit implementation, as shown in
registers use fewer than eight bits. Their bit definitions are shown in
Figure
The PORTnP/SETn registers are read/write. At reset, the bits in the PORTnP/SETn registers are set to the
current pin states.
Reading a PORTnP/SETn register returns the current state of the port n pins.
Setting a PORTnP/SETn register sets the corresponding bits in the PORTn register. Writing 0s has no
effect.
