11.5.3.2 Output Mapping
In contrast to inputs, the outputs of the Peripheral Pin
Select options are mapped on the basis of the pin. In
this case, a control register associated with a particular
pin dictates the peripheral output to be mapped. The
RPORx registers are used to control output mapping.
Each register contains two 6-bit fields, with each field
being associated with one RPn pin (see Register 11-32
through Register 11-46). The value of the bit field
corresponds to one of the peripherals and that
peripheral’s output is mapped to the pin (see
Table 11-7).
Because of the mapping technique, the list of peripherals
for output mapping also includes a null value of ‘000000’.
This permits any given pin to remain disconnected from
the output of any of the pin-selectable peripherals.
