Bit NAME Meaning Default
2 reserved Not Supported, always 0 0
1 reserved Not Supported, always 0 0
0 reserved Not Supported, always 0 0
STATUS_CML (7Eh)
The STATUS_CML command is a standard PMBus
™
command that returns the value of a number of flags
related to communication faults. Accesses to this command should use the PMBus
™
read byte protocol. To clear
bits in this register, a CLEAR_FAULTS command should be issued.
Table 14. STATUS_CML Definitions
Bit NAME Default
7 Invalid or unsupported command received 0
6 Invalid or unsupported data received 0
5 Packet Error Check failed 0
4 Memory Fault Detected Not supported, always 0 0
3 Processor Fault Detected Not supported, always 0 0
2 Reserved, always 0 0
1 Miscellaneous communications fault has occurred 0
0 Other memory or logic fault detected Not supported, always 0 0
STATUS_OTHER (7Fh)

0 Not supported: Always 0 0
STATUS_MFR_SPECIFIC (80h)
The STATUS_MFR_SPECIFIC command is a standard PMBus
™
command that contains manufacturer specific
status information. Accesses to this command should use the PMBus
™
read byte protocol. To clear bits in this
register, the underlying fault should be removed and a CLEAR_FAULTS command should be issued. The default
loaded status does not create an SMB Alert State.
