3.1 DUAL-PORT RAM MEMORY MAP
The internal 2816-byte (2560-byte on REV A and B mask) dual-port RAM is partitioned to
1792 bytes (1536 bytes on REV A and B mask) of system RAM, 256-byte microcode scratch
area, and 768 bytes of parameter RAM (see Table 3-1). Its base address, called dual-port
RAM base (DPRBASE), is the address pointed to by the MBAR.
NOTE
Rev A mask is C63T, Rev B mask are C69T, and F35G
The system RAM may be used for microcode program area, data area, and buffer descrip-
tors (BDs). It may be partitioned in several ways, allowing programmable partition sizes to
fit the system requirements. This is described in Section 7 Communication Processor Mod-
ule (CPM).
