Figure 7-1. Comparator Mode

As shown in Figure 7-2, in Alert mode (Alert_Mode = 1b), the ALERT pin and status flag become active when

the temperature equals or exceeds the THigh_Limit for Fault number of consecutive conversion. The ALERT

pin/flag remains active until a read operation of any register occurs or the device responds to the SMBus

Alert Response. When the ALERT pin and status flag are cleared, the pin/flag becomes active only when the

temperature is less than the TLow_Limit for Fault number of consecutive conversion, and remains active until a

read operation of any register occurs or the device responds to the SMBus Alert Response. When the ALERT

pin/flag is cleared after a TLow_Limit crossing, the above cycle repeats. The ALERT pin and status flag can also

be cleared by issuing the General Call Reset command.
