PIC18F47J13 FAMILY
11.2
The primary mode of operation for the module is
configured using the MODE<1:0>
PMMODEH register. The setting affects whether the
module acts as a slave or a master and it determines
the usage of the control pins.
11.2.1
In
PMPEN = 1), the module is configured as a Parallel
Slave Port (PSP) with the associated enabled module

pins dedicated to the module. In this mode, an external
device, such as another microcontroller or micro-
processor, can asynchronously read and write data
using the 8-bit data bus (PMD<7:0>), the read (PMRD),
write (PMWR) and chip select (PMCS) inputs. It acts as
a slave on the bus and responds to the read/write
control signals.
Figure 11-2 displays the connection of the PSP.
When chip select is active and a write strobe occurs
(PMCS = 1 and PMWR = 1), the data from
PMD<7:0> is captured into the PMDIN1L register.
