Description
Reserved
These bits are reserved; they are always read as 0
and cannot be modified.
Description
Reserved
If these bits are read, they will return an undefined
value.
Output data for a pin is stored when the pin function
is specified to a general purpose I/O.
If a port H read is performed while PHDDR bits are
set to 1, the PHDR values are read. If a port H read
is performed while PHDDR bits are cleared to 0, the
pin states are read.
