† _{These C64x™ devices have two EMIFs (64-bit EMIFA and 16-bit EMIFB). The prefix “A” in front of a signal name indicates it is an}
EMIFA signal whereas a prefix “B” in front of a signal name indicates it is an EMIFB signal. Throughout the rest of this document,
in generic EMIF areas of discussion, the prefix “A” or “B” may be omitted from the signal name.
