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

Note 1:
Writes to PORTE are actually written to corresponding LATE register. Reads from PORTE register is
return of actual I/O pin values.

. 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.
