12.10. Consecutive ALERT register

The consecutive ALERT register is used to choose how many times an out-of-limit (≥ High Limit or < Low Limit)

condition have been detected in consecutive measurements before the

_____

ALERT or

______

THERM /ADDR pin is

asserted. Additionally, the TIMEOUT bit (B7) is used to enable or disable the SMBus timeout.

When an out-of-limit condition is detected in consecutive measurements, the consecutive alert counter will be

increased by 1. The counter will be reset if no out-of-limit condition occurs in a consecutive measurement.

When the

_____

ALERT pin is configured in the interrupt mode, if the consecutive alert counter reaches its

programmed value, the STATUS bit and the last out-of-limit condition will be set to ‘1’. And the

_____

ALERT pin will

be asserted. Then the consecutive alert counter will be cleared.

When the

_____

ALERT pin is configured in comparator mode, the consecutive alert counter will be increased by 1

only when the measured temperature exceeds the High Limit. Once the consecutive alert counter reaches the

programmed limit, the

_____

ALERT pin will be asserted. However, the consecutive alert counter will not be reset. And

it will remain set until the temperature drops below the High Limit minus the Therm Hysteresis.

TIMEOUT

0 (default): The SMBus Timeout function is disabled. The device will not resetting its SMBus protocol

even the SMCLK line being held low indefinitely.

1: The SMBus Timeout function is enabled. The device will reset the SMBus protocol if the SMCLK line is

held low for more than 30 ms.

CTHRM

[2:0]

Determines the number of consecutive temperature measurements that must exceed the corresponding

Therm Limit before the

_____

THERM/ADDR pin is asserted. The consecutive therm counter will be increased

by 1 whenever the temperature measurement exceed the Therm Limit.

Once the measured temperature drops below the Therm Limit, the corresponding therm counter is reset.

Once the

_____

THERM /ADDR pin has been asserted, the therm counter will not reset until the measured

temperature drops below the Therm Limit minus the Therm Hysteresis.
