DMA Mode Register (DMODE: I/O Address = 31h)
PS014004-1106
Bit
Mnemonic DMODE
Address 31h
DM1, DM0: Destination Mode Channel 0 (bits 5,4)—Specifies whether the
destination for channel 0 transfers is memory or I/O, and whether the address must be incre-
mented or decremented for each byte transferred.
