10.7.3.2 Output Mapping
In contrast to inputs, the outputs of the PPS options are
mapped on the basis of the pin. In this case, a control reg-
ister associated with a particular pin dictates the periph-
eral output to be mapped. The RPORx registers are used
to control output mapping. The value of the bit field corre-
sponds to one of the peripherals and that peripheral’s
output is mapped to the pin (see Table 10-14).
Because of the mapping technique, the list of
peripherals 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.

Note 1: Value assigned to the RP<4:0> pins corresponds to the peripheral output function number.
2: The NULL function is assigned to all RPn outputs at device Reset and disables the RPn output function.
