SLUS625D – SEPTEMBER 2004 – REVISED OCTOBER 2005
0 = SBS.RemainingCapacity( ) is not modified on valid charge termination
1 = SBS.RemainingCapacity( ) is written up to equal SBS.FullChargeCapacity( ) on valid charge
termination .
NRCHG
Enables the charge FET to remain on during sleep when DF:Operation Cfg B [NR] is set
0 = Charge FET turns off in Sleep (default)
1 = Charge FET remains on in Sleep
NCSMB
Enables extended SMBUS tTIMEOUT
0 = Normal SMBUS tTIMEOUT (default)
1 = Extended SMBUS tTIMEOUT
RESCAP
This bit configures the compensation model for the DF:Reserve Cap-mAh and DF:Reserve
Cap-10mWh.
0 = Light Load (C/20) Compensation
1 = SBS.AverageLoad( ) Compensation
PFD1,0
Configure the Permanent Failure LED display (disabled if SBS.Operation Cfg A [SLED] = 1)

SCD
The DF:Non-Removable Cfg bits enable the current protection recovery features to be treated differently based
on DF:Operation Cfg A [NR]. The additional recovery features are detailed with the individual features in the 1st
Level Safety section of this data sheet.
SCD
= Short Circuit in Discharge
SCC
= Short Circuit in Charge
AOCD
= AFE Overcurrent in Discharge
OCC2
= Overcurrent in Charge - Tier 2
OCD2
= Tier-2 Overcurrent, Discharge
OCC
= Overcurrent in Charge
OCD
= Overcurrent in Discharge
PF Flags 1
The permanent failure flags 1 register indicates the reason that bq20z80 has entered permanent failure.
