Status Registers - Analog Devices ADM1060 Manual

ADM1060
those of the fault registers with the exception that the
ANYFLT bit cannot be masked. Setting a 1 in the error
mask register results in the equivalent bit in the fault reg-
ister always remaining at 0, regardless of whether there is a
fault on that function or not. The register and bit maps for
both the fault and error mask registers are shown below.
