15.3.2 PORTE on 28-Pin Devices
For PIC18(L)F2xK40 devices, PORTE is
only available when Master Clear functionality is disabled (MCLRE = 0). In this case, PORTE
is a single bit, input-only port comprised of RE3 only. The pin operates as previously
described. RE3 in PORTE register is a read-only bit and will read ‘1
’ when MCLRE = 1
(i.e., Master Clear enabled).
