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
register associated with a particular pin dictates the
peripheral output to be mapped. The RPORx registers
are used to control output mapping. The value of the bit
field corresponds 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
disconnected from the output of any of the pin
selectable peripherals.

2: The NULL function is assigned to all RPn outputs at device Reset and disables the RPn output function.
