Formula used to calculate voltage reference:
VRR = 1 (low range)
CVref = ([VR3:VR0]/24)VLADDER
VRR = 0 (high range)
CVref = (VLADDER/4) + ([VR3:VR0]VLADDER/32)
Vladder = Vdd or ([Vref+] - [Vref-]) or Vref+
Step 3 - Starting operation:
● Enable interrupt by setting bits CMIE (PIE register), PEIE and GIE (both in the INTCON register);
● Read bits C1OUT and C2OUT of the CMCON register; and
● Read flag bit CMIF of the PIR register. After being set, this bit must be cleared in software.
