PORTE and TRISE Registers
PORTE has three pins, RE0/RD/AN5, RE1/WR/AN6
and RE2/CS/AN7, which are individually configured as
inputs or outputs. These pins have Schmitt Trigger
input buffers.
I/O PORTE becomes control inputs for the micropro-
cessor port when bit PSPMODE (TRISE<4>) is set. In
this mode, the user must make sure that the
TRISE<2:0> bits are set (pins are configured as digital
inputs) and that register ADCON1 is configured for dig-
ital I/O. In this mode, the input buffers are TTL.
Register 5-1 shows the TRISE register, which also con-
trols the parallel slave port operation.
PORTE pins may be multiplexed with analog inputs
(PIC16C765 only). The operation of these pins is
selected by control bits in the ADCON1 register. When
selected as an analog input, these pins will read as ’0’s.
TRISE controls the direction of the RE pins, even when
they are being used as analog inputs. The user must
make sure to keep the pins configured as inputs when
using them as analog inputs.
TRISE bits are used to control the parallel slave port.

Note 1: The
PIC16C745
does
not
provide
PORTE. The PORTE and TRISE registers
are reserved. Always maintain these bits
clear.
Note:
On a Power-on Reset, these pins are con-
figured as analog inputs.
