10.3.4 Port 3 Open Drain Control Register (P3ODR)
P3ODR controls the output status for each port 3 pin.
Bit Bit Name Initial Value R/W Description
7, 6 ⎯ All 0 ⎯ Reserved
These bits are always read as 0 and cannot be
modified.
5 P35ODR 0 R/W
4 P34ODR 0 R/W
3 P33ODR 0 R/W
2 P32ODR 0 R/W
1 P31ODR 0 R/W
Setting a P3ODR bit to 1 makes the corresponding
port 3 pin an NMOS open-drain output pin, while
clearing the bit to 0 makes the pin a CMOS output
pin.
0 P30ODR 0 R/W
