Section 7 Data Transfer Controller (DTC)
7.2
7.2.1
MRA is an 8-bit register that controls the DTC operating mode.
Bits 7 and 6—Source Address Mode 1 and 0 (SM1, SM0): These bits specify whether SAR is
to be incremented, decremented, or left fixed after a data transfer.
Bit 7
SM1
0
1
Bits 5 and 4—Destination Address Mode 1 and 0 (DM1, DM0): These bits specify whether
DAR is to be incremented, decremented, or left fixed after a data transfer.

Description
SAR is fixed
SAR is incremented after a transfer
(by 1 when Sz = 0; by 2 when Sz = 1)
SAR is decremented after a transfer
(by 1 when Sz = 0; by 2 when Sz = 1)
Description
DAR is fixed
DAR is incremented after a transfer
(by 1 when Sz = 0; by 2 when Sz = 1)
DAR is decremented after a transfer
(by 1 when Sz = 0; by 2 when Sz = 1)
