32.8.18 DMAC Channel x [x = 0..7] Configuration Register
Name: 
DMAC_CFGx [x = 0..7]
Addresses:
0xFFFFEC50 [0], 0xFFFFEC78 [1], 0xFFFFECA0 [2], 0xFFFFECC8 [3], 0xFFFFECF0 [4], 0xFFFFED18 [5], 
0xFFFFED40 [6], 0xFFFFED68 [7]
Access:

This register can only be written if the WPEN bit is cleared in 
• SRC_PER: Source with Peripheral identifier
Channel x Source Request is associated with peripheral identifier coded SRC_PER handshaking interface.
• DST_PER: Destination with Peripheral identifier
Channel x Destination Request is associated with peripheral identifier coded DST_PER handshaking interface.
• SRC_REP: Source Reloaded from Previous
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: Software or Hardware Selection for the Source
0 (SW): Software handshaking interface is used to trigger a transfer request.
1 (HW): Hardware handshaking interface is used to trigger a transfer request.
• SRC_PER_MSB: SRC_PER Most Significant Bits
This field indicates the Most Significant bits of the SRC_PER field.
• DST_REP: Destination Reloaded from Previous
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 previous 
transfer.
• DST_H2SEL: Software or Hardware Selection for the Destination
0 (SW): Software handshaking interface is used to trigger a transfer request.
1 (HW): Hardware handshaking interface is used to trigger a transfer request.
