NOTE: 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)].
A. ARE/SDCAS/SADS/SRE, AWE/SDWE/SWE and AOE/SDRAS/SOE operate as SDCAS, SDWE, and SDRAS,
respectively, during SDRAM accesses.
