20.3.11
Buffered Parallel Slave Port mode is functionally iden-
tical to the Legacy Parallel Slave Port mode with one
exception: the implementation of 4-level read and write
buffers. Buffered Slave mode is enabled by setting the
PMMODE<INCM1:INCM0> bits to ‘11’.
FIGURE 20-9:
20.3.12
The Buffered Slave mode configuration is determined
automatically and dedicated to the PMP module when
the Buffered Slave mode is selected. The user only
need to configure the polarity of the PMCS1, PMRD
and PMWR signals.
The following example illustrates which control bits are
to be set for Buffered Slave mode configuration:
• Configure Buffered Slave mode bits -
• Select PMRD “active-low” pin polarity -
• Select PMWR “active-low” pin polarity -
• Select PMCS2, PMCS1 “active-low” pin polarity -
20.3.13
The Buffered Slave mode initialization properly
prepares the PSP port for communicating with an
external master device.
The following steps should be performed to properly
configure the PSP port:

INCM<1:0> (PMMODE<12:11>) = 11.
MODE<1:0> (PMMODE<9:8>) = 00 and
RDSP (PMCON<0>) = 0.
WRSP (PMCON<1>) = 0.
CS2P (PMCON<4>) = 0 and CS1P
(PMCON<3>) = 0.
If interrupts are used, disable the PMP interrupt
by clearing the interrupt enable bit PMPIE
(IEC1<2>) = 0.
Stop and reset the PMP module by clearing the
control bit ON (PMCON<15>) = 0.

When the Buffered mode is active, the module uses the
PMDIN register as write buffers and the PMDOUT reg-
ister as read buffers, with respect to the master device.
Each register is divided into four 8-bit buffer registers,
four read buffers in PMDOUT and four write buffers in
PMDIN. Buffers are numbered 0 through 3, starting
with the lower byte <7:0> and progressing upward
through the high byte <31:24>.
