DAC Interaction without DMA

After 256 DAC clock cycles data will be read from the FIFOs and will begin being

processed by the D/A.

Once data is transferred from the FIFO another DAC interrupt is generated and the

CPU will again process the interrupt and transfer new data into the DAC data

registers. This process continues until the DAC module is shut down or if the device

is put into sleep mode.
