23.6
Port H is a 5-bit input/output port with the pin configuration shown in figure 23.6. Each pin has an
input pull-up MOS, which is controlled by the port H control register (PHCR) in the PFC.
23.6.1
Port H has the following register. Refer to section 27, List of Registers, for the address of this
register and state of this register in each processing mode.
• Port H data register (PHDR)
23.6.2
PHDR is a 5-bit readable/writable register that stores data for pins PTH4 to PTH0. Bits PH4DT to
PH0DT correspond to pins PTH4 to PTH0. When the 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.
If the TE or RE bit is set to 1 in the serial control register _1 (SCSCR_1) of the serial
communication interface with FIFO (SCIF), the SCIF1_TxD or SCIF1_RxD is selected regardless
of the PHCR register setting.
