The reference points for the rise and fall transitions are measured at VOL MAX and VOH MIN.
These C64x
devices have two EMIFs (64-bit EMIFA and 16-bit 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 = the EMIF input clock (ECLKIN, CPU/4 clock, or CPU/6 clock) period in ns for EMIFA or EMIFB.
N = the EMIF input clock divider; N = 1, 2, or 4.
This cycle-to-cycle jitter specification was measured with CPU/4 or CPU/6 as the source of the EMIF input clock.
