TMS320C6211/C6711 Operation: ARDY is sampled for the first time on
the ECLKOUT cycle at the end of the programmed strobe period. If
sampled low, the strobe period is extended and ARDY is sampled again
on the next ECLKOUT cycle. Read data is latched by the 'C6211 on the
cycle that ARDY is sampled high. The ARE signal goes high on the the
following cycle. Therefore, the strobe period is visibly extended by three
cycles in Figure 9–44, although data is latched by the 'C6211 after the sec-
ond cycle.
