3.6.2 Feature Enable/Disable
The feature is enabled when DFETF is set in Enable PF C.
3.7 Instruction Flash (IF) Checksum Permanent Fail
The device can permanently disable the battery if it detects a difference between the stored IF checksum and
the calculated IF checksum only following a device reset.
Status Condition Action
Normal Stored and calculated IF checksum match —
Trip Stored and calculated IF checksum after reset does not match.
PFStatus()[IFC] = 1
BatteryStatus()[TCA] = 1
BatteryStatus()[TDA] = 1
3.8 Data Flash (DF) Permanent Fail
The device can permanently disable the battery in case a data flash write fails.
Note
A DF write failure causes the gauge to disable further DF writes.
Status Condition Action
Normal Data flash write ok —
Trip Data flash write not successful
PFStatus()[DFW] = 1
BatteryStatus()[TCA] = 1
BatteryStatus()[TDA] = 1
