In the Addressable Parallel Slave Port mode
(
two extra inputs, PMA<1:0>, which are the address
lines 1 and 0. This makes the 4-byte buffer space
directly addressable as fixed pairs of read and write
buffers. As with legacy Buffered mode, data is output
from PMDOUT1L, PMDOUT1H, PMDOUT2L and
PMDOUT2H, and is read in PMDIN1L, PMDIN1H,
PMDIN2L and PMDIN2H. Table 11-2 shows the buffer
addressing for the incoming address to the input and
output registers.
