• SRC_PER
Channel x Source Request is associated with peripheral identifier coded SRC_PER handshaking interface.
• DST_PER
Channel x Destination Request is associated with peripheral identifier coded DST_PER handshaking interface.
• SRC_REP
0 (CONTIGUOUS_ADDR): When automatic mode is activated, source address is contiguous between two buffers.
1 (RELOAD_ADDR): When automatic mode is activated, the source address and the control register are reloaded from
previous transfer.
• SRC_H2SEL
0 (SW): Software handshaking interface is used to trigger a transfer request.
1 (HW): Hardware handshaking interface is used to trigger a transfer request.
• DST_REP
0 (CONTIGUOUS_ADDR): When automatic mode is activated, destination address is contiguous between two buffers.
1 (RELOAD_ADDR): When automatic mode is activated, the destination and the control register are reloaded from the pre-
vious transfer.
• DST_H2SEL
0 (SW): Software handshaking interface is used to trigger a transfer request.
1 (HW): Hardware handshaking interface is used to trigger a transfer request.
