Section 10 I/O Ports
10.1.4
P1ODR specifies the output type of each port 1 pin.
10.1.5
Port 1 pins also function as the pins for PPG outputs, TPU I/Os, EXDMAC I/Os (H8S/2426,
H8S/2426R), SSU I/Os, and DMAC I/Os (H8S/2424). The correspondence between the register
specification and the pin functions is shown below.

The pin function is switched as shown below according to the combination of the operating
mode, bit EXPE, TPU channel 2 settings (by bits MD3 to MD0 in TMDR_2, bits IOB3 to
IOB0 in TIOR_2, and bits CCLR1 and CCLR0 in TCR_2), bits TPSC2 to TPSC0 in TCR_0
and TCR_5, bit NDER15 in NDERH of the PPG, bit EDRAKE in EDMDR_3 of the
EXDMAC, bits MSS, CSS1, and CSS0 in SSCRH and bit SSUMS in SSCRL of the SSU, bits
SCS0S1 and SCS0S0 in PFCR5, and bit P17DDR.

Description
Setting a P1ODR bit to 1 makes the corresponding
pin an NMOS open-drain output pin, while clearing
a P1ODR bit to 0 makes the corresponding pin a
CMOS output pin.
