6.5.5 Read Strobe (RD
The read strobe (RD) timing can be changed for individual areas by setting bits RDN7 to RDN0 to
1 in RDNCR. Figure 6.18 shows an example of the timing when the read strobe timing is changed
in basic bus 3-state access space.
When the DMAC is used in single address mode, note that if the RD timing is changed by setting
RDNn to 1, the RD timing will change relative to the rise of DACK.
