Description
Addressing this function sets the DAC registers to the clear code and updates the outputs.
Addressing this function updates the DAC registers and, consequently, the DAC outputs.
Set by the user to disable the SDO output. Cleared by the user to enable the SDO output (default).
See Table 26 for a description of the CLR select operation.
Set by the user to enable the current limit clamp (default). The channel does not power down on detection of
overcurrent; the current is clamped at 20 mA.
Cleared by the user to disable the current-limit clamp. The channel powers down on detection of overcurrent.
Set by the user to enable the thermal shutdown feature. Cleared by the user to disable the thermal shutdown
feature (default).
