DMA Activation Source Flag Control Register (DMCSL)
This bit selects whether the interrupt flag of the activation source of the DMAC is cleared to 0 or issues an interrupt to
the CPU, at the beginning of transfer.
When DMTMD.DCTG[1:0] = 00b (activation by software), the setting of the DISEL bit does not affect the operation.
