Command Register
This 8-bit write-only register prescribes DMA operations for all MSM82C37B-5 channels. An
outline of all bits is given in Figure 3. When the controller is disabled by setting D B2, there is
no HRQ output even if DMA request is active.
DREQ and DACK signals may be active high or active low by setting D B6 and DB7.
DB7
0: Memory-Memory Transfer Disabled
1: Memory-Memory Transfer Enabled
DB6
DB5
DB4
DB3
DB2
DB1
DB0
0: Channel 0 Address Hold Disabled
1: Channel 0 Address Hold Enabled
0: Controller Enabled
1: Controller Disabled
0: Normal Timing
1: Compressed Timing
0: Fixed Priority
1: Rotating Priority
0: Normal Write Pulse Width
1: Extended Write Pulse Width
0: DREQ Sense Active "H"
1: DREQ Sense Active "L"
0: DACK Sense Active "L"
1: DACK Sense Active "H"
