PORTE and TRISE Register
(PIC16C661 and PIC16C662 only)
PORTE has three pins RE0/RD, RE1/WR, and RE2/
CS, which are individually congurable 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 congured 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.

bit 7:
IBF: 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
bit 6:
OBF: Output Buffer Full Status bit
1 = The output buffer still holds a previously written word
0 = The output buffer has been read
bit 5:
IBOV: Input Buffer Overow 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 overow occurred
bit 4:
PSPMODE: Parallel Slave Port Mode Select bit
1 = Parallel slave port mode
0 = General purpose I/O mode
bit 3:
Unimplemented: Read as '0'
bit 2:
TRISE2: Direction control bit for pin RE2/CS
1 = Input
0 = Output
bit 1:
TRISE1: Direction control bit for pin RE1/WR
1 = Input
0 = Output
bit 0:
TRISE0: Direction control bit for pin RE0/RD
1 = Input
0 = Output
