• Bits 15–14—Source Address Mode 1, 0 (SM1, SM0): These bits designate whether to hold,

increment, or decrement the DTSAR after a data transfer.

Bit 15 (SM1)

Bit 14 (SM0)

Description

—

DTSAR remains fixed

DTSAR is incremented after transfer

(+1 for byte unit transfer, +2 for word, +4 for longword)

DTSAR is decremented after transfer

(–1 for byte unit transfer, –2 for word, –4 for longword)

• Bits 13–12—Destination Address Mode 1, 0 (DM1, DM0): These bits designate whether to

hold, increment or decrement the DTDAR after a data transfer.

Bit 13 (DM1)

Bit 12 (DM0)
