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 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.
