RE<2:0> are not implemented on the PIC16F1933/1936/1938. Read as ‘0’.
TRISE<2:0> are not implemented on the PIC16F1933/1936/1938/PIC16LF1933/1936/1938. Read as ‘0’.
Unimplemented: Read as ‘0’
RE<3:0>: PORTE I/O Pin bits
1 = Port pin is > V
0 = Port pin is < V
Unimplemented: Read as ‘0’
TRISE3: RE3 Port Tri-state Control bit
This bit is always ‘1’ as RE3 is an input only
TRISE<2:0>: RE<2:0> Tri-State Control bits
1 = PORTE pin configured as an input (tri-stated)
0 = PORTE pin configured as an output
