Section 8 Data Transfer Controller (DTC)
8.2
8.2.1
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.
