Note 1:
Pin
2:
OUT = Output, IN = Input, ANA = Analog Signal, DIG = Digital Output, ST = Schmitt Buffer Input,
TTL = TTL Buffer Input, x = Don’t care (TRIS bit does not affect port direction or is 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.
All other pin functions are disabled when ICSP™ or ICD operation is enabled.
