The port H IO register (PHIOR) is a 16-bit readable/writable register that selects the input/output
direction of pins in port H. Bits PH1IOR and PH0IOR correspond to pins PH1/DA1 to PH0/DA0.
PHIOR is enabled when port H pins function as general input/output pins (PH1 and PH0), and
disabled otherwise.
When port H pins function as PH1 and PH0, a pin becomes an output when the corresponding bit
in PHIOR is set to 1, and an input when the bit is cleared to 0.
PHIOR is initialized to H'0000 by an external power-on reset, but is not initialized by a WDT
reset, in standby mode, or in sleep mode.

The port H control register (PHCR) is a 16-bit readable/writable register that selects the functions
of pins in port H. PHCR selects the functions of port H pins PH1/DA1 and PH0/DA0.
