4.2 Sensor Thresholds
The AM4022 CPU module is available for two different operating temperature ranges. For each
operating temperature range, a set of temperature thresholds for the sensors is defined. The
standard temperature range uses thresholds defined by Table 11, and the extended tempera-
ture range uses thresholds defined by Table 12. Table 13 provides voltage sensor thresholds.
