9.7
Port H is a 1-bit input and 4-bit I/O port. Port H has the following registers.
• Port H data direction register (PHDDR)
• Port H data register (PHDR)
• Port H register (PORTH)
9.7.1
PHDDR specifies input or output the port H pins using the individual bits. PHDDR cannot be
read; if it is, an undefined value will be read.
The value of this register when read is undefined after a bit manipulation instruction is executed.
To prevent undefined read values, do not use bit manipulation instructions to write to this register.
For details, see section 2.9.4, Access Methods for Registers with Write-Only Bits.

Description
Reserved
These bits are always read as undefined value and
cannot be modified.
When a pin is specified as a general purpose I/O port,
setting these bits to 1 makes the corresponding port H
pin an output pin. Clearing this bit to 0 makes the pin an
input pin.
