174 / 406 page ![]() PIC24FJ128GA310 FAMILY DS39996F-page 174 2010-2011 Microchip Technology Inc. 11.4.3.1 Input Mapping The inputs of the Peripheral Pin Select options are mapped on the basis of the peripheral; that is, a control register associated with a peripheral dictates the pin it will be mapped to. The RPINRx registers are used to configure peripheral input mapping (see Register 11-7 through Register 11-26). Each register contains two sets of 6-bit fields, with each set associated with one of the pin-selectable peripher- als. Programming a given peripheral’s bit field, with an appropriate 6-bit value, maps the RPn/RPIn pin with that value to that peripheral. For any given device, the valid range of values for any of the bit fields corre- sponds to the maximum number of Peripheral Pin Selections supported by the device.
