SA56004X
Digital temperature sensor with overtemperature alarms
Event C: The Status register bit 1 (RCRIT) is reset by a read of the Status register (in 
the interrupt mode).
7.9.3   Fault Queue
To suppress erroneous ALERT
 or T_CRIT
 triggering, the SA56004X implements a Fault
Queue for both local and remote channel. The Fault Queue insures a temperature
measurement is genuinely beyond a HIGH, LOW or T_CRIT setpoint by not triggering
until three consecutive out-of-limit measurements have been made. The fault queue
defaults OFF upon POR and may be activated by setting bit 0 in the Configuration register
(address 09h) to logic 1.
 
Event A: The remote temperature has exceeded the Remote HIGH setpoint.
Event B: Three consecutive over limit measurements have been made exceeding the 
Remote HIGH setpoint; the ALERT
 output is activated (goes LOW). By now, the remote
temp has exceeded the Remote T_CRIT setpoint (RCS).
Event C: Three consecutive over limit measurements have been made exceeding RCS; 
the T_CRIT
 output is activated (goes LOW).
Event D: The remote temperature falls below the RCS - TH setpoint.
Event E: The ALERT
 output is de-activated (goes HIGH) after a below_high_limit
temperature measurement is completed.
Remark: All events indicate the completion of a conversion.
