7.5.8 Open Drain Output Control Register
BWOMH — Port B Open-Drain Mode (H)
When this bit is set, the upper four bits (7–4) of port B pins that are configured as outputs become
open-drain outputs. This bit is cleared on reset.
BWOML — Port B Open-Drain Mode (L)
When this bit is set, the lower four bits (3–0) of port B pins that are configured as outputs become
open-drain outputs. This bit is cleared on reset.
Bits 5–3 — Reserved
These bits are not used and always read zero.
CWOM — Port C Open-Drain Mode
When this bit is set, port C pins that are configured as outputs become open-drain outputs. This bit is
cleared on reset.
AWOM — Port A Open-Drain Mode (High Nibble)
When this bit is set, the upper four bits of port A that are configured as outputs become open-drain
outputs. This bit is cleared on reset.
Bit 0 — Reserved
This bit is not used and always returns to zero.
