Description
Data Transfer Master Enable 4
Together with the DTE4 bit, this bit controls
enabling or disabling of data transfer on channel 4.
When both the DTME4 bit and DTE4 bit are set to
1, transfer is enabled for channel 4.
If channel 4 is in the middle of a burst mode
transfer when an NMI interrupt is generated, the
DTME4 bit is cleared to 0, the transfer is
interrupted, and bus mastership is passed to the
CPU. When the DTME4 bit is subsequently set to 1
again, the interrupted transfer is resumed. In block
transfer mode, however, the DTME4 bit is not
cleared by an NMI interrupt, and transfer is not
interrupted.
