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 two
5-bit fields; each field being associated with one RPn
pin (see Register 9-15 through Register 9-27). The
value of the bit field corresponds to one of the periph-
erals and that peripheral’s output is mapped to the pin
(see Table 9-2).

Because of the mapping technique, the list of peripher-
als for output mapping also includes a null value of
‘00000’. This permits any given pin to remain discon-
nected from the output of any of the pin selectable
peripherals.
