Mask Register
This register is used in disabling and enabling of DMA transfers in each channel. Each channel
includes a corresponding mask bit in the mask register, and each bit is set when the TC is reached
if not in autoinitialize mode. This mask register can be set in two different ways.
The method for setting/resetting the register for each channel is outlined in Figure 6(a), while
the method for setting/resetting the register for all channels at once is outlined in Figure 6(b).
