The DMA Interrupt Request Mask Register is used to mask interrupt requests on each DMA channel.
(1) DMITMKn (DMAn Interrupt Request Mask) bit (n = 0–9)
Setting the DMAn interrupt request mask bit to "1" masks the interrupt requests on DMAn channel. However,
if an interrupt request occurs, the DMAn interrupt request status bit is always set to "1" irrespective of the
contents of this mask register.
