The PMP module offers two Master modes of operation
featuring 16-bit or 8-bit data (default), up to 16 bits of
address, and all control signals to operate a variety of
external parallel devices such as memory devices,
peripherals, and slave microcontrollers. An example
using Master Mode 2 is shown in Figure 20-2.

Preliminary
20.2.3
The two Master modes are selected using MODE<1:0>
bits (PMCON<9:8>). Master Mode 1 is selected by con-
figuring MODE<1:0> bits = 11; Master Mode 2 is
selected by configuring MODE<1:0> bits = 10.
20.2.4
The PMP in Master mode supports data widths 8 and
16 bits wide. By default, the data width is 8-bit,
MODE16 (PMMODE<10>) bit = 0. To select 16-bit data
width, set MODE16 = 1. When configured in 8-Bit Data
mode, the upper 8 bits of the data bus, PMD<15:8>, are
not controlled by the PMP module and are available as
general purpose I/O pins.
20.2.5
Two Chip Select lines, PMCS1 and PMCS2, are avail-
able for the Master modes. The two Chip Select lines
are multiplexed with the Most Significant bits of the
address bus A14 and A15. If a pin is configured as a
Chip Select, it is not included in any PMA<15:0>
address auto-increment/decrement. It is possible to
enable both PMCS2 and PMCS1 as Chip Selects, or
enable only PMCS2 as a Chip Select, allowing PMCS1
to function strictly as address line A14. It is not possible
to enable only PMCS1. The Chip Select signals are
configured using the Chip Select Function bits
CSF<1:0> (PMCON <7:6>).
TABLE 20-3:
Refer to Section 20.2.16 “Addressing Consider-
ations” for information regarding Chip Select address
mapping.
20.2.6
The PMAEN register controls the functionality of the
address pins PMA<15:0>. Setting any PMAEN bit = 1
configures the corresponding PMA pin as an address
line. Those bits set = 0 remain as general purpose I/O
pins.
Refer to Section 20.5 “I/O Pin Control” regarding I/O
pin configuration.
