Chapter 9 I/O Module

9-6

As mentioned previously, each of the multi-function I/O ports can be independently programmed for

routing of signals for a standard/normal function to or from any given multi-function I/O port. Table

9.2.1 lists each of these standard functions for each multi-function I/O port. Note that depending on the

reset state for the respective MFIO Select Register bits, the pin function is configured either as a multi-

function port or as a standard function port.
