PORTE is a 1-bit, 4-bit or 8-bit port with Schmitt Trigger
input buffers. RE<7:4, 2:0> are individually configured as
inputs or outputs and RE3 is only available as an input if
MCLRE is ‘0’ in Configuration Word (Register 16-1).
RE<2:0> are only available on the PIC16F914/917 and
PIC16F946. RE<7:4> are only available on the
PIC16F946.
