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.
