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

associated with one RPn pin (see Register 9-10

through Register 9-17). The value of the bit field

corresponds to one of the peripherals, and that

peripheral’s output is mapped to the pin (see Table 9-2

and Figure 9-3).

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.
