SLUS625D – SEPTEMBER 2004 – REVISED OCTOBER 2005
This read-word function returns indications of pending safety issues, such as when safety timers have started, or
fail counters are nonzero but have not reached the required time or value to trigger an SBS.SafetyStatus( )
change. The bit arrangement follows that of SBS.SafetyStatus( ). See the SBS.SafetyStatus( ) and 1st Level
Safety sections of the data sheet for further details.
This read-word function returns the current status of the safety functions.

This read-word function returns indications of pending permanent failure issues, such as when safety timers have
started, or fail counters are nonzero, but have not reached the required time or value to trigger a DF:Permanent
Failure Status change. The bit arrangement follows that of SBS.PFStatus( ) except for [AFE_C] and [AFE_P] as
these have no alert. See the SBS.PFStatus( ), DF:PFStatus and Secondary Protection Features sections of the
data sheet for further details.
The permanent failure status register indicates the source of the bq20z80 permanent-failure condition. The bit
arrangement follows that of DF:PF Flags 1. See the DF:PF Flags 1 and 2nd Level Safety sections of the data
sheet for further details.
When any new cause of PF is detected in SBS.PFStatus( ), the new cause is added to DF:PF Flags 1. This
allows DF:PF Flag 1 to show ALL of the different PF conditions that have occurred. On the first occasion of
SBS.PFStatus( ) changing from 0x00 the value is stored to DF:PF Flag 2.
This read-word function returns the current status of the operation status of the bq20z80.
