8.6.8
When a transfer is aborted by clearing the DTE bit or suspended by an NMI that clears the DTME
bit, if this halts a channel for which the DMAC has a transfer request pending internally, a dead
cycle may occur. This dead cycle does not update the halted channel’s address register or counter
value. Figure 8.27 shows an example in which an auto-requested transfer in cycle-steal mode on
channel 0 is aborted by clearing the DTE bit in channel 0.
