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 - 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.
External Diode Fault Register
Channel Mask Register
‘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.
