PORTE and TRISE Register
PORTE and TRISE are not implemented on the
PIC16F873 or PIC16F876.
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.
The PORTE pins become the I/O control inputs for the
microprocessor port when bit PSPMODE (TRISE<4>) is
set. In this mode, the user must make certain that the
TRISE<2:0> bits are set, and that the pins are configured
as digital inputs. Also ensure that ADCON1 is configured
for digital I/O. In this mode, the input buffers are TTL.
Register 3-1 shows the TRISE register, which also con-
trols the parallel slave port operation.
PORTE pins are multiplexed with analog inputs. When
selected for 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.
Note:
On a Power-on Reset, these pins are con-
figured as analog inputs, and read as ‘0’.
