Output Mapping

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 sets
of 6 bit fields, with each set associated with one RPn
pin (see 

 through 

). The

value of the bit field corresponds to one of the periph-
erals and that peripheral’s output is mapped to the pin
(see 

).

A null output is associated with the Output Register
Reset value of ‘0’. This is done to ensure that remap-
pable outputs remain disconnected from all output pins
by default.
