12.10. Channel mask register

The channel mask register is used to determine whether the individual channel is masked or not. When a

channel is masked, the

_____

ALERT pin will not be asserted even when the masked channel detects a fault or out of

limit error. Note that the channel mask can only mask the

_____

ALERT pin in the interrupt mode. No matter the

channel mask bit is set or not, the status registers will be updated normally.

12.11. Consecutive ALERT register

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

condition or fault 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 or fault condition is detected on the same temperature channel in consecutive

measurements, the consecutive alert counter for that channel will be increased by 1. Each counter will be reset if

no out-of-limit condition or fault condition occurs in a consecutive measurement.

When the

_____

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

programmed value, the STATUS bit for the corresponding channel and the last out-of-limit condition or fault

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.
