7.0 Wait Support
(Continued)
7.2 PAGE ACCESSES
During page accesses, DTACK (and CAS) will assert from
either clock edge according to programming bit ECAS2.
Figure 22 shows different DTACK assertions during page
accesses, they follow an opening access with 1 wait state.
DTACK and CAS assert on the rising edge of clock.

FIGURE 22c. DTACK is Programmed 1T for Openings and 2T during Page
TL/F/11718–19
FIGURE 22d. DTACK is Programmed 1T for Openings and 3T during Page
Note:
DTACK is programmed to assert from a positive clock edge.
