Name of Byte ............. <Read/Write><Nonvolitile><Factory-Default-Setting>
Threshold0
Temp High Alarm ..... <R-all/W-pw2><NV><7FFFh> Temperature measurements above this
two's complement threshold set its corresponding alarm bit.
Measurements below this threshold clear the alarm bit.
Temp Low Alarm....... <R-all/W-pw2><NV><8000h> Temperature measurements below this
two's complement threshold set its corresponding alarm bit.
Measurements above this threshold clear the alarm bit.
Temp High Warning . <R-all/W-pw2><NV><7FFFh> Temperature measurements above this
two's complement threshold set its corresponding warning bit.
Measurements below this threshold clear the warning bit.
Temp Low Warning .. <R-all/W-pw2><NV><8000h> Temperature measurements below this
two's complement threshold set its corresponding warning bit.
Measurements above this threshold clear the warning bit.
Threshold1
VCC High Alarm........ <R-all/W-pw2><NV><FFFFh> Voltage measurements of the VCC
input above this unsigned threshold set its corresponding alarm bit.
Measurements below this threshold clear the alarm bit.
VCC Low Alarm.......... <R-all/W-pw2><<NV><0000h> Voltage measurements of the VCC
input below this unsigned threshold set its corresponding alarm bit.
Measurements above this threshold clear the alarm bit.
VCC High Warning.... <R-all/W-pw2><NV><FFFFh> Voltage measurements of the VCC
input above this unsigned threshold set its corresponding warning
bit. Measurements below this threshold clear the warning bit.
VCC Low Warning..... <R-all/W-pw2><<NV><0000h> Voltage measurements of the VCC
input below this unsigned threshold set its corresponding warning
bit. Measurements above this threshold clear the warning bit.
Threshold2
Mon1 High Alarm ..... <R-all/W-pw2><NV><FFFFh> Voltage measurements of the Mon1
input above this unsigned threshold set its corresponding alarm bit.
Measurements below this threshold clear the alarm bit.
Mon1 Low Alarm ...... <R-all/W-pw2><NV><0000h> Voltage measurements of the Mon1
input below this unsigned threshold set its corresponding alarm bit.
Measurements above this threshold clear the alarm bit.
Mon1 High Warning. <R-all/W-pw2><NV><FFFFh> Voltage measurements of the Mon1
input above this unsigned threshold set its corresponding warning
bit. Measurements below this threshold clear the warning bit.
Mon1 Low Warning .. <R-all/W-pw2><NV><0000h> Voltage measurements of the Mon1
input below this unsigned threshold set its corresponding warning
bit. Measurements above this threshold clear the warning bit.
