DISRCn Bit Description Initial State
LOC [1] Bit 1 is used to select the location of source.
0 = The source is in the system bus (AHB),
1 = The source is in the peripheral bus (APB)
0
INC [0] Bit 0 is used to select the address increment.
0 = Increment
1 = Fixed
If it is 0, the address is increased by its data size after each transfer
in burst and single transfer mode.
If it is 1, the address is not changed after the transfer (In the burst
mode, address is increased during the burst transfer, but the
address is recovered to its first value after the transfer).
