When set, disables an LPC abort response from clearing the DMA
request. When clear, LPC abort response is treated normally.
R/W
0
26
When set, disables an LPC error response from clearing the DMA request.
When clear, LPC error response is treated normally.
R/W
0
25
When set, disables requests from memory for masked channels. When
clear, requests are treated normally.
R/W
0
24
When set, disables writes to the master clear register from clearing the
DMA request. When clear, DMA behaves normally.
R/W
