The IOM-2 ports can be configured to Push-Pull or Open-Drain modes by a dedicated
bit in the IOMU Control Register. When programmed to Open-Drain, DD0/DD1 is tri-
stated when a ‘1’ is supposed to be transmitted, or during a time slot quadruplet with the
associated Tri-State Register bit set.
In both cases the external pull-up resistor, which is used when working in open-drain
mode, will “pull” the value to ‘1’.
Note: When the IOMU is programmed to 1x 64 time slots per frame mode, DD1 is tri-
