(1) 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
programmable synchronous interface access signals are shown as generic (SADS/SRE, SOE, and SWE) instead of ASADS/ASRE,
ASOE, and ASWE (for EMIFA) and BSADS/BSRE, BSOE, and BSWE (for EMIFB)].
