PORTE and TRISE Register
This section is not applicable to the PIC16CR73 or
PIC16CR76.
PORTE has three pins, RE0/RD/AN5, RE1/WR/AN6
and RE2/CS/AN7, which are individually configureable
as inputs or outputs. These pins have Schmitt Trigger
input buffers.
I/O PORTE becomes control inputs for the micro-
processor 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). Ensure ADCON1 is configured for digital I/O. In
this mode, the input buffers are TTL.
Register 4-1 shows the TRISE register, which also
controls the Parallel Slave Port operation.
PORTE pins are multiplexed with analog inputs. 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.

(IN I/O PORT MODE)
Note:
On a Power-on Reset, these pins are
configured as analog inputs and read as
‘0’.
