PIC16F7X7
5.5
This section is not applicable to the PIC16F737 or
PIC16F767.
PORTE has four pins, RE0/RD/AN5, RE1/WR/AN6,
RE2/CS/AN7 and MCLR/V
ally configureable as inputs or outputs. These pins have
Schmitt Trigger input buffers. RE3 is only available as an
input if MCLRE is ‘0’ in Configuration Word 1.
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 5-1 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.

ST = Schmitt Trigger input, TTL = TTL input
Input buffers are Schmitt Triggers when in I/O mode and TTL buffers when in Parallel Slave Port mode.
x = unknown, u = unchanged, — = unimplemented, read as ‘0’. Shaded cells are not used by PORTE.
RE3 is an input only. The state of the TRISE3 bit has no effect and will always read ‘1’.
On a Power-on Reset, these pins are
configured as analog inputs and read as ‘0’.
