The DMA0-4 Interrupt Mask Register is used to mask interrupt requests in DMA channels 0-4.
DMITMKn (DMAn interrupt request mask) bit (n = 0 to 4)
DMAn interrupt request is masked by setting the DMAn interrupt request mask bit to 1. However,
when an interrupt request is generated, the DMAn interrupt request status bit is always set to 1
irrespective of the contents of this register.
