DATASHEET

Unlike the ALERT pin, the THERM pin cannot be masked. Additionally, the THERM pin will be released

once the temperature drops below the corresponding threshold minus the Therm Hysteresis.

External Diode Fault Register

The External Diode Fault Register indicates which of the external diodes caused the FAULT bit in the

Status Register to be set. This register is cleared when it is read.

Bit 3 - E3FLT (EMC1414 only) - This bit is set if the External Diode 3 channel reported a diode fault.

Bit 2 - E2FLT - This bit is set if the External Diode 2 channel reported a diode fault.

Bit 1 - E1FLT - This bit is set if the External Diode 1 channel reported a diode fault.

7.11

Channel Mask Register

The Channel Mask Register controls individual channel masking. When a channel is masked, the

ALERT pin will not be asserted when the masked channel reads a diode fault or out of limit error. The

channel mask does not mask the THERM pin.

Bit 3 - E3MASK (EMC1414 only) - Masks the ALERT pin from asserting when the External Diode 3

channel is out of limit or reports a diode fault.

‘0’ (default) - The External Diode 3 channel will cause the ALERT pin to be asserted if it is out of
