Implemented only when Master Clear functionality is disabled (MCLRE Configuration bit = 0).
RE3 is the only PORTE bit implemented on both PIC18F2XK20 and PIC18F2XK20 devices. All other bits
are implemented only when PORTE is implemented (i.e., PIC18F4XK20 devices).
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).
RE3 is available on both PIC18F2XK20 and PIC18F4XK20 devices. All other PORTE pins are only implemented on
PIC18F4XK20 devices.
RE3 does not have a corresponding TRIS bit to control data direction.
