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.
5 P35ODR 0 R/W When OE-B/CKE-B* 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.
Note: Not supported in the H8S/2456 Group and H8S/2454 Group.
