6.2.9 Pin Output RP Registers

Register RPnR shows the RP Remap Register format for output functions. See RPnR from Related Links. Each RP pin has a 4-bit field that can be assigned to the desired output function. See the following tables for a complete list of output function values and associated register names.

The mapping is dynamic; therefore, to avoid glitching outputs, the user must ensure that the appropriate peripherals are turned off before remapping the functions. On Reset, all inputs are mapped to a default value and all outputs are disabled; therefore, the mapping must be performed after any device Reset.
