PIC16(L)F1938/9
REGISTER 12-20: LATE: PORTE DATA LATCH REGISTER

bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set ‘0’ = Bit is cleared
bit 7-4 Unimplemented: Read as ‘0’
bit 3-0 LATE<3:0>: PORTE Output Latch Value bits
(1)
Note 1: Writes to PORTE are actually written to corresponding LATE register. Reads from PORTE register is
return of actual I/O pin values.
2: LATE register is not implemented on the PIC16(L)F1938. Read as ‘0’
REGISTER 12-21: ANSELE: PORTE ANALOG SELECT REGISTER

bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
u = bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set ‘0’ = Bit is cleared
bit 7-3 Unimplemented: Read as ‘0’
bit 2-0 ANSE<2:0>: Analog Select between Analog or Digital Function on Pins RE<2:0>, respectively
0 = Digital I/O. Pin is assigned to port or digital special function.
1 = Analog input. Pin is assigned as analog input
(1)
. Digital input buffer disabled.
Note 1: When setting a pin to an analog input, the corresponding TRIS bit must be set to Input mode in order to
allow external control of the voltage on the pin.
2: ANSELE register is not implemented on the PIC16(L)F1938. Read as ‘0’
