Function of PINMODE in open drain mode
Normally the value of PINMODE applies to a pin only when it is in the input mode. When a
pin is in the open drain mode, caused by a 1 in the corresponding bit of one of the
PINMODE_OD registers, the input mode still does not apply when the pin is outputting a
0. However, when the pin value is 1, PINMODE applies since this state turns off the pin’s
output driver. For example, this allows for the possibility of configuring a pin to be open
drain with an on-chip pullup. A pullup in this case which is only on when the pin is not
being pulled low by the pin’s own output.
