SV – Supply Voltage (VDD) Flag
•
0 = Supply voltage is within specification.
•
1 = Supply voltage is outside of specification.
•
HV1 – Heater Voltage Flag
•
0 = Heater voltage is within specification.
•
1 = Heater voltage is outside of specification.
•
OS1 – Open Sensor Flag
•
0 = Sensor is connected.
•
1 = Sensor is not connected.
•
HV2 and OS2 are reserved bits. In case of write access, you should set to “0”.
*
If you want to read flag register, it is recommended to read twice in order to avoid conflict with the
MCU update.
