EXAMPLE 20-5:
20.3.14
In the Addressable Parallel Slave Port mode, the mod-
ule is configured with two extra inputs, PMA<1:0>. This
makes the 4-byte buffer space directly addressable as
fixed pairs of read and write buffers. As with Buffered
Legacy mode, data is output from register PMDOUT
and is input to register PMDIN. Table 20-10 shows the
address resolution for the incoming address to the
input and output registers.
FIGURE 20-10:
20.3.15
The Addressable Slave mode configuration is deter-
mined automatically and dedicated to the PSP module
when the Addressable Slave mode is selected. The
user only need to configure the polarity of the PMCS1,
PMRD and PMWR signals.
to be set for Addressable Slave mode configuration:
• Configure Addressable Slave mode bits –
