DIG = Digital level output; TTL = TTL input buffer; ST = Schmitt Trigger input buffer; ANA = Analog level input/output;
x = Don’t care (TRIS bit does not affect port direction or is overridden for this option).
All other pin functions are disabled when ICSP or ICD is enabled.
Single-Supply Programming must be enabled.
RD5 is the alternate pin for PWM4.
