Section 9 Bus Controller (BSC)
9.6.7
When the DMAC or EXDMAC transfers data in single address mode, the output timing of the
DACK and EDACK signals can be changed by the DKC and EDKC bits in BCR1.
Figure 9.24 shows the output timing of the DACK and EDACK signals. The DACK and EDACK
signals are asserted a half cycle earlier by setting the DKC or EDKC bits to 1.
