Description
Data Transfer Master Enable 1
Together with the DTE1 bit, this bit controls
enabling or disabling of data transfer on
channel 1. When both the DTME1 bit and DTE1
bit are set to 1, transfer is enabled for channel
1.
If channel 1 is in the middle of a burst mode
transfer when an NMI interrupt is generated, the
DTME1 bit is cleared, the transfer is interrupted,
and bus mastership passes to the CPU. When
the DTME1 bit is subsequently set to 1 again,
the interrupted transfer is resumed. In block
transfer mode, however, the DTME1 bit is not
cleared by an NMI interrupt, and transfer is not
interrupted.
[Clearing conditions]
[Setting condition]
When 1 is written to DTME1 after reading
DTME1 = 0
When initialization is performed
When NMI is input in burst mode
When 0 is written to the DTME1 bit
