Description
Data Transfer Master Enable 0
Together with the DTE0 bit, this bit controls
enabling or disabling of data transfer on channel 0.
When both the DTME0 bit and DTE0 bit are set to
1, transfer is enabled for channel 0.
If channel 0 is in the middle of a burst mode
transfer when an NMI interrupt is generated, the
DTME0 bit is cleared, the transfer is interrupted,
and bus mastership passes to the CPU. When the
DTME0 bit is subsequently set to 1 again, the
interrupted transfer is resumed. In block transfer
mode, however, the DTME0 bit is not cleared by an
NMI interrupt, and transfer is not interrupted.
