23.8.2
PHDR is a 15-bit readable/writable register with one reserved bit that stores data for pins PTH14
to PTH0. PHDR is initialized to H'0000 by a power-on reset, but it retains its previous value by a
manual reset, in standby mode, or in sleep mode.

Description
Reserved
This bit is always read as 0. The write value should
always be 0.
Bits PH14DT to PH0DT correspond to pins PTH14 to
PTH0. When the pin function is general output port, the
value of the corresponding bit in PHDR is returned
directly by reading the port. When the function is
general input port, the corresponding pin level is read
by reading the port. Table 23.11 shows the function of
PHDR.
