Bit 3 - E3FLT - 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.
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 - Masks the ALERT pin from asserting when the External Diode 3 channel is out of
limit or reports a diode fault.
Bit 2 - E2MASK - Masks the ALERT pin from asserting when the External Diode 2 channel is out of
limit or reports a diode fault.
Bit 1 - E1MASK - Masks the ALERT pin from asserting when the External Diode 1 channel is out of
limit or reports a diode fault.
Bit 0 - INTMASK - Masks the ALERT pin from asserting when the Internal Diode temperature is out
of limit.

‘0’ (default) - The External Diode 3 channel will cause the ALERT pin to be asserted if it is out of
limit or reports a diode fault.
‘1’ - The External Diode 3 channel will not cause the ALERT pin to be asserted if it is out of limit
or reports a diode fault.
‘0’ (default) - The External Diode 2 channel will cause the ALERT pin to be asserted if it is out of
limit or reports a diode fault.
‘1’ - The External Diode 2 channel will not cause the ALERT pin to be asserted if it is out of limit
or reports a diode fault.
‘0’ (default) - The External Diode 1 channel will cause the ALERT pin to be asserted if it is out of
limit or reports a diode fault.
‘1’ - The External Diode 1 channel will not cause the ALERT pin to be asserted if it is out of limit
or reports a diode fault.
‘0’ (default) - The Internal Diode channel will cause the ALERT pin to be asserted if it is out of limit.
‘1’ - The Internal Diode channel will not cause the ALERT pin to be asserted if it is out of limit.
