Section 35
35.8.2
PHDR is a register that stores data for pins PTH6 to PTH0. Bits PH6DT to PH0DT correspond to
pins PTH6 to PTH0. When the pin function is general output port, if the port is read, the value of
the corresponding PHDR bit is returned directly. When the function is general input port, if the
port is read, the corresponding pin level is read.

Description
Reserved
This bit is always read as 0. The write value should always
be 0.
Table 35.8 shows the function of PHDR.
Write
Value is written to PHDR, but does not affect
pin state.
Write value is output from pin.
Value is written to PHDR, but does not affect
pin state.
Value is written to PHDR, but does not affect
