These C64x devices have two EMIFs (EMIFA and EMIFB). All EMIFA signals are prefixed by an “A” and all EMIFB signals are prefixed by a
“B”. Throughout the rest of this document, in generic EMIF areas of discussion, the prefix “A” or “B” may be omitted [e.g., the synchronous DRAM
memory access signals are shown as generic ( SDCAS, SDWE, and SDRAS ) instead of ASDCAS, ASDWE, and ASDRAS (for EMIFA) and
BSDCAS, BSDWE, and BSDRAS (for EMIFB)].
