Legend:

Note 1:

2:

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 PORTE pins are only implemented on 40/44-pin devices.

RE3 does not have a corresponding TRIS bit to control data direction.

— = unimplemented, read as ‘0’. Shaded cells are not used by PORTE.

Implemented only when Master Clear functionality is disabled (CONFIG3H<7> = 0). It is available for

PIC18F4331/4431 devices only.

ANS5 through ANS8 are available only on PIC18F4331/4431 devices.
