The Port 4 Open-Drain register defines the output driver type for Port 4. If a bit of Port 4 has been
configured as an output and the corresponding bit in the Port 4 Open-Drain register is a 1, the Port 4 bit
will have an open-drain output driver. If it is a 0, the Port 4 bit will have a push-pull output driver. If the
bit of Port 4 has been configured as an input, the corresponding bit is the Port 4 Open-Drain register has
no effect.

The Port 2/3 A Mode, Port 2/3 B Mode, Port 2/3 C Mode and Port 2/3 D Mode registers control the
modes of Ports 2 and 3. A separate 2-bit field for each of the bits of Ports 2 and 3 configures the bit as
input or output. The field also controls whether the bit is enabled as an external interrupt source and
selects the oputpus as open-drain or push-pull.
