Operation
The pullups are tied to the physical pin pad and not to the function. So, for example, if the
AUART1_TX pullup is enabled, that pullup will be present on the AUART1_TX pin
regardless of what function (AUART1_TX, IR_TX, or SSP1_DATA7) is pin multiplexed
out of that pin.
The table below lists which function (not which pin name), an internal pullup has been
implemented, to assist in the hardware interfaces' operation.
