Section 9 I/O Ports
9.13.2
PHDR stores output data for the port H pins.
9.13.3
PORTH shows the pin states. It cannot be modified.
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.

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 PHDDR bits are
set to 1, the PHDR values are read. If this register read
is performed while PHDDR bits are cleared to 0, the pin
states are read.
