Threshold
3
• Mon2 High Alarm..... <R-all/W-pw2><NV><FFFFh> Voltage measurements of the Mon2
input above this unsigned threshold set its corresponding alarm bit.
Measurements below this threshold clear the alarm bit.
• Mon2 Low Alarm ...... <R-all/W-pw2><NV><0000h> Voltage measurements of the Mon2
input below this unsigned threshold set its corresponding alarm bit.
Measurements above this threshold clear the alarm bit.
• Mon2 High Warning. <R-all/W-pw2><NV><FFFFh> Voltage measurements of the Mon2
input above this unsigned threshold set its corresponding warning
bit. Measurements below this threshold clear the warning bit.
• Mon2 Low Warning .. <R-all/W-pw2><NV><0000h> Voltage measurements of the Mon2
input below this unsigned threshold set its corresponding warning
bit. Measurements above this threshold clear the warning bit.
Threshold
4
• Mon3 High Alarm..... <R-all/W-pw2><NV><FFFFh> Voltage measurements of the Mon3
input above this unsigned threshold set its corresponding alarm bit.
Measurements below this threshold clear the alarm bit.
• Mon3 Low Alarm ...... <R-all/W-pw2><NV><0000h> Voltage measurements of the Mon3
input below this unsigned threshold set its corresponding alarm bit.
Measurements above this threshold clear the alarm bit.
• Mon3 High Warning. <R-all/W-pw2><NV><FFFFh> Voltage measurements of the Mon3
input above this unsigned threshold set its corresponding warning
bit. Measurements below this threshold clear the warning bit.
• Mon3 Low Warning .. <R-all/W-pw2><NV><0000h> Voltage measurements of the Mon3
input below this unsigned threshold set its corresponding warning
bit. Measurements above this threshold clear the warning bit.
User ROM
• User ROM ................. <R-all/W-pw2><NV><00h> Nonvolatile EEPROM memory.
A2D Value
