PIC18F6525/6621/8525/8621
10.10 Parallel Slave Port
PORTD also operates as an 8-bit wide Parallel Slave
Port, or microprocessor port, when control bit
PSPMODE (PSPCON<4>) is set. It is asynchronously
readable and writable by the external world through RD
control input pin, RE0/RD and WR control input pin,
RE1/WR.
The PSP can directly interface to an 8-bit micro-
processor data bus. The external microprocessor can
read or write the PORTD latch as an 8-bit latch. Setting
bit PSPMODE enables port pin RE0/RD to be the RD
input, RE1/WR to be the WR input and RE2/CS to be
the CS (chip select) input. For this functionality, the
corresponding data direction bits of the TRISE register
(TRISE<2:0>) must be configured as inputs (set). The
A/D
(ADCON1<2:0>), must be set, which will configure pins
RE2:RE0 as digital I/O.
A write to the PSP occurs when both the CS and WR
lines are first detected low. A read from the PSP occurs
when both the CS and RD lines are first detected low.
The PORTE I/O pins become control inputs for the micro-
processor port when bit PSPMODE (PSPCON<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) and the ADCON1 is configured for digital I/O. In
this mode, the input buffers are TTL.
