data. May be configured for tri-state during Enhanced PWM shutdown events.
Legend:
Note 1:
PWR = Power Supply, O = Output, I = 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).
Alternate assignments for P1B/P1C and P3B/P3C when ECCPMX configuration bit is cleared. Default assignments are
PORTE<6:3>.
