19.8 SLRCONx - Slew Rate Control
The SLRCONx register controls the slew rate option for each PORT
            pin. Slew rate for each PORT pin can be controlled independently. When a SLRCONx bit is
            set (SLRCONx = 1), the corresponding PORT pin drive is slew rate
            limited. When a SLRCONx bit is cleared (SLRCONx = 0), the corresponding
            PORT pin drive slews at the maximum rate possible.
