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 WPUE: Weak Pull-up Register bit
1 = Pull-up enabled
0 = Pull-up disabled
bit 2-0 Unimplemented: Read as ‘0’
Note 1: Global WPUEN
bit of the OPTION_REG register must be cleared for individual pull-ups to be enabled.
2: The weak pull-up device is automatically disabled if the pin is in configured as an output.

Legend: x = unknown, u = unchanged, – = unimplemented locations read as ‘0’. Shaded cells are not used by
PORTE.
Note 1: These bits are not implemented on the PIC16(L)F1938 devices, read as ‘0’.
2: Unimplemented, read as ‘1’.
