I
overridden for this option)
Configuration on POR is determined by PBADEN Configuration bit. Pins are configured as analog inputs when
PBADEN is set and digital inputs when PBADEN is cleared.
Alternate pin assignment for CCP2 when CCP2MX = 0. Default assignment is RC1.
All other pin functions are disabled when ICSP™ or ICD operation is enabled.
40/44-pin devices only.
