Alarm Status 0 Register Field Descriptions Bit Field Type Reset Description 7-5 Reserved R All zeros Reserved for factory use 4 ADC20-ALR R 0 ADC20-ALR = 1 when ADC20 is out of the range defined by the corresponding threshold registers. ADC20-ALR = 0 when the analog input is not out of the specified range. 3 ADC19-ALR R 0 ADC19-ALR = 1 when ADC19 is out of the range defined by the corresponding threshold registers. ADC19-ALR = 0 when the analog input is not out of the specified range. 2 ADC18-ALR R 0 ADC18-ALR = 1 when ADC18 is out of the range defined by the corresponding threshold registers. ADC18-ALR = 0 when the analog input is not out of the specified range. 1 ADC17-ALR R 0 ADC17-ALR = 1 when ADC17 is out of the range defined by the corresponding threshold registers. ADC17-ALR = 0 when the analog input is not out of the specified range. 0 ADC16-ALR R 0 ADC16-ALR = 1 when ADC16 is out of the range defined by the corresponding threshold registers. ADC16-ALR = 0 when the analog input is not out of the specified range. 7.6.9.2 Alarm Status 1 Register (address = 0x71) [reset = 0x00] Figure 96. Alarm Status 1 Register (R) 7 6 5 4 3 2 1 0 Reserved ALARMIN-ALR THERM-ALR LT-HIGH-ALR LT-LOW-ALR R-All zeros R-0 R-0 R-0 R-0 Table 44. Alarm Status 1 Register Field Descriptions Bit Field Type Reset Description 7-4 Reserved R All zeros Reserved for factory use 3 ALARMIN-ALR R 0 The ALARMIN-ALR is set to 1 if the ALARMIN pin is enabled and set high. 2 THERM-ALR R 0 Thermal alarm flag. When the die temperature is equal to or greater than +150°C, the bit is set (1) and the THERM-ALR flag activates. The on-chip temperature sensor (LT) monitors the die temperature. If LT is disabled, the THERM-ALR bit is always 0. The hysteresis of this alarm is 8°C. 1 LT-HIGH-ALR R 0 LT-HIGH-ALR = 1 when the temperature sensor is out of the range defined by the upper threshold. 0 LT-LOW-ALR R 0 LT-LOW-ALR = 1 when the temperature sensor is out of the range defined by the lower threshold. |
