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.
Each register contains two 6-bit fields, with each field
being associated with one RPn pin (see Register 9-22
through Register 9-37). The value of the bit field

Setting the RPORx register with the listed value assigns that output function to the associated RPn pin.
The NULL function is assigned to all RPn outputs at device Reset and disables the RPn output function.

corresponds to one of the peripherals 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
‘000000’. This permits any given pin to remain discon-
nected from the output of any of the pin selectable
peripherals.
