18.8.1
Port H has the following register. Refer to section 23, List of Registers, for more details of the
addresses and access sizes.
18.8.2
Port H data register (PHDR) is a 7-bit read/write and 1-bit read register that stores data for pins
PTH6 to PTH0. PH6DT to PH0DT bit corresponds to PTH6 to PTH0 pin. 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.
PHDR is initialized to H'00 by a power-on reset. It retains its previous value in standby mode and
sleep mode, and in a manual reset.
Note that the low level is read if bits 6 to 0 are read except in general-purpose input.
