Description
An output data for a pin is stored when the pin function
is specified to a general purpose output port.
Description
If this register read is performed while PDDDR bits are
set to 1, the PDDR values are read. If this register read
is performed while PDDDR bits are cleared to 0, the pin
states are read.
Reading a pin being used as an LCD driver returns an
undefined value.
