Masks all ALERT interrupts when high.
Standby mode control bit. If high, the device immediately stops converting and enters
standby mode. If low, the device converts in either one-shot or timer mode.
Should be 0. Changing this to 1 will cause ALERT function abnormal.
Validation of the fault queue function of thermal shutdown.
Fault Queue. Number of faults necessary to detect before setting TH_SHUT output to
avoid false tripping due to noise.
