10.3.4 Port 3 Open Drain Control Register (P3ODR)
P3ODR specifies the output type of each port 3 pin.
Bit Bit Name Initial Value R/W Description
7, 6 ⎯ All 0 ⎯ Reserved
These bits are always read as 0. Only the initial
values should be written to these bits.

output is not selected,
setting this bit to 1 makes the corresponding pin an
NMOS open-drain output pin, while clearing the bit
to 0 makes the corresponding pin a CMOS output
pin.
4 P34ODR 0 R/W
3 P33ODR 0 R/W
2 P32ODR 0 R/W
1 P31ODR 0 R/W
0 P30ODR 0 R/W
Setting a bit to 1 makes the corresponding pin an
NMOS open-drain output pin, while clearing a bit to
0 makes the corresponding pin a CMOS output pin.
Notes: 1. Not supported in the 5-V version.
2. Not supported in the H8S/2426 Group and H8S/2424 Group.
