Offers maximum versatility for automatic input

monitoring. An interrupt mask selects which inputs

cause an interrupt on transitions, and transition flags

identify which inputs have changed (even if only for a

transient) since the ports were last read.

12 push-pull outputs with selectable default logic

levels.

Open-drain outputs can level shift the logic-high

state to a higher or lower voltage than V+ using

external pullup resistors, but pullups draw current

when output is low. Any open-drain port can be used

as an input by setting the open-drain output to logic-

high. Transition flags identify which open-drain port

inputs have changed (even if only for a transient)

since the ports were last read.
