Table 4. FMEA Analysis (Note 6) (continued)
Note 6: If the cell voltage is within the monitor range, the heartbeat signal on ALRM
Note 7: The voltage level of high is equal to V
Note 8: Even if the pin has internal pulldown, the pulldown is very weak and the pin should be tied to AGND for logic 0 setting.
