MAR is incremented after a data transfer
• When DTSZ = 0, MAR is incremented
by 1 after a transfer
• When DTSZ = 1, MAR is incremented
by 2 after a transfer
1
MAR is decremented after a data transfer
• When DTSZ = 0, MAR is decremented
by 1 after a transfer
• When DTSZ = 1, MAR is decremented
by 2 after a transfer
