8.6.5
The read strobe timing can be modified in area units by setting bits RDN7 to RDN0 in RDNCR to
1.
Note that the RD timing with respect to the DACK rising edge will change if the read strobe
timing is modified by setting RDNn to 1 when the DMAC is used in the single address mode.
Figure 8.21 shows an example of timing when the read strobe timing is changed in the basic bus 3-
state access space.
