VID_SEL = GND.
Selecting the HAMMER DAC, the device checks for VID code modifications on the rising
edge of a clock that is the same frequency of each phase and waits for a confirmation on the
following falling edge. Once the new code is stable, on the next rising edge the reference
starts stepping up or down in LSB increments (25mV) every clock cycle until the new VID
code is reached. During the transition, VID code changes are ignored; the device re-starts
monitoring VID after the transition has finished on the next rising edge.
If the new VID code is more than 1 bit higher than the previous, the device will execute the
transition stepping the reference every switching cycle until the new code has reached
