In a DRAM access cycle, wait states can be inserted (1) between the T
between the T
Insertion of T
by setting the RCW bit to 1 in DRCRB.
Insertion of T
area designated as DRAM space is set to 1, from 0 to 3 T
state and T
Figure 6.18 shows an example of the timing for wait state insertion.
The settings of the RCW bit in DRCRB and of ASTCR, WCRH, and WCRL do not affect refresh
cycles. Wait states cannot be inserted in a DRAM space access cycle by means of the WAIT pin.
