Destination is the block area in block transfer mode
Source is the block area in block transfer mode
Description
MARB is held fixed
MARB is incremented after each data transfer
• If DTSZ = 0, MARB is incremented by 1 after each data transfer
• If DTSZ = 1, MARB is incremented by 2 after each data transfer
MARB is held fixed
MARB is decremented after each data transfer
• If DTSZ = 0, MARB is decremented by 1 after each data transfer
• If DTSZ = 1, MARB is decremented by 2 after each data transfer
