PRODUCTION DATA
The DAC_UPDATE_BUSY bit (address D0h) is set to 1 by the device when certain DAC update operations, such as function generation, transition to margin high or low, or any of the medical alarms are in progress. When the DAC_UPDATE_BUSY bit is set to 1, do not write to any of the DAC registers. After the DAC update operation is completed (DAC_UPDATE_BUSY = 0), any of the DAC registers can be written.
