STATUS_IOUT (7Bh)

TheSTATUS_IOUTcommandreturns1byteofinforma-

tion with contents, as described in Table 21. All the bits in

STATUS_IOUT are latched. When cleared, the bits are

set again if the condition persists.

STATUS_TEMPERATURE (7Dh)

TheSTATUS_TEMPERATUREcommandreturns1byte

of information with contents, as described in Table 22. All

thebitsinSTATUS_VOUTarelatched.Whencleared,the

bits are set again if the condition persists.

STATUS_CML (7Eh)

TheSTATUS_CMLcommandreturns1byteofinforma-

FAULT, DATA_FAULT, MAIN_FAULT, and BACKUP_

again when theevent occurs again.TheFAULT_LOG_

FULLbitreflectsthecurrentreal-timestateofthefaultlog.

Notes: When the NV fault log overwrite is enabled (NV_LOG_OVERWRITE = 1 in MFR_MODE), FAULT_LOG_FULL is set when the

fault log is full, but clears when the fault log is overwritten since two fault logs are cleared before each overwrite; the setting of the

BACKUP_FAULT and MAIN_FAULT bits do not assert the ALERT signal.
