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.

Like the RPINRx registers, each register contains sets

of 5-bit fields, with each set associated with one RPn

pin (see Register 11-17 through Register 11-29). The

value of the bit field corresponds to one of the

peripherals, and that peripheral’s output is mapped to

the pin (see Table 11-2 and Figure 11-3).

The list of peripherals for output mapping also includes

a null value of ‘00000’

because of the mapping

technique. This permits any given pin to remain

unconnected from the output of any of the pin

selectable peripherals.
