One nice feature of the STM32 is the ability to use an external pin to clock
data out of the DACs via DMA.
i.e. you can set up a block of samples (S&H data, audio waveform, etc.) to
be cyclically loaded into the DAC, and have an external signal (e.g. PLL'd
analogue oscillator) drive the output at a variable sample rate with no CPU
overhead.
