  • Page 94: Alert Registers

    OPT100 User Guide M211858EN-K A.4.2 Alert registers Gas level alert registers are 16-bit fields. Each register communicates the status of alerts of specific severity for a particular timeframe (for example, gas level caution alerts for present values). If an alert is active, the corresponding bit is set to 1. The bit is set to 0 when the alert is deactivated, turned off, or gas level alerts are muted.
