Description
MARB is held fixed
(Initial value)
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
Bit 3âTransfer Mode Select (TMS): Selects whether the source or destination is the block area
in block transfer mode.
