These values are communicated to the
function by passing a single command-value pair or a sequence of pairs in
a table terminated with the

For example, to bypass the built-in voltage regulator, the following code
could be used.
adi_pwr_SetVoltageRegulator(ADI_PWR_SET_VR_FREQ,
(void*) ADI_PWR_VR_FREQ_POWERDOWN);
The following table defines the command-value pairs that can be used
with the
