STATUS REGISTER
Address Pointer 0x00
8 Bits, Read-Only, Default Value 0x53 Before Conversion, 0x52 After Conversion
The status register indicates the status of the part. The register can be read via the 2-wire serial interface to query the status of the outputs,
check the CDC finished conversion, and check whether the CAPDAC has been changed by the autoCAPDAC function.

Description
7
PwrDown
PwrDown = 1 indicates that the part is in a power-down mode or that the part VDD is below the power supply
monitor threshold voltage.
6
Bit not used, always reads 1.
5
Bit not used, always reads 0.
4
DacStep
DacStep = 0 indicates that the CAPDAC value was changed during the last conversion as part of the AutoDac
function. The bit value is updated after each finished CDC conversion.
3
OUT
OUT = 1 indicates that the data (CIN capacitance) crossed the threshold, according to the selected comparator
mode of operation. The bit value is updated after each finished CDC conversion.
2
Bit not used, always reads 0.
1
Bit not used, always reads 1.
0
RDY
RDY = 0 indicates a finished CDC conversion. The bit is reset back to 1 when the data register is read via the
serial interface or after the part reset or power-up.
