Legend: Shaded cells are not used by PORTE.
Note 1: These bits are unimplemented on 44-pin devices, read as ‘0’.

Setting
I/O I/O Type Description
Legend: O = Output, I = Input, ANA = Analog Signal, DIG = CMOS Output, ST = Schmitt Trigger Buffer Input,
x = Don’t care (TRIS bit does not affect port direction or is overridden for this option)
Note 1: These bits are unavailable for 40 and 44-pin devices (PIC18F4XK0).
2: This is the alternate pin assignment for CANRX and CANTX on 64-pin devices (PIC18F6XK80) when the CANMX
Configuration bit is cleared.
