PORTE and TRISE Register
(PIC16C661 and PIC16C662 only)
PORTE has three pins RE0/RD, RE1/WR, and RE2/
CS, which are individually configurable 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). In this mode the input buffers are TTL.
Figure 5-9 shows the TRISE register, which also con-
trols the parallel slave port operation.

Input Buffer Full Status bit
1 = A word has been received and waiting to be read by the CPU
0 = No word has been received
OBF
: Output Buffer Full Status bit
1 = The output buffer still holds a previously written word
0 = The output buffer has been read
IBOV
: Input Buffer Overflow Detect bit (in microprocessor mode)
1 = A write occurred when a previously input word has not been read (must be cleared in software)
0 = No overflow occurred
PSPMODE
: Parallel Slave Port Mode Select bit
1 = Parallel slave port mode
0 = General purpose I/O mode
Unimplemented
