A.1.2.10 Permanent Fail Clear(PFkey)
This 2 step command needs to be written to ManufacturerAccess in following order: 1st word of the PFKey followed by the 2nd word of the PFKey. The default 1st word is 0x2673 and the default 2nd word is 0x1712.
It instructs the bq20z70 to clear the PFStatus, clear the [PF] flag, reset the SAFE pin and unlock the dataflash for writes.
This command is only available when the bq20z70 is in Unsealed or Full Access mode.

· DFF Statusevice Status Data(96):PF Flags 2(28)
· SBS:PFStatus(0x46)
· SBS:SafetyStatus(0x51)[PF]
· SBS:PFKey(0x62)
Note: Higher 2 bytes must be immediately followed by lower 2 bytes. If clear command fails,command can only be repeated 4 seconds after previous attempt. If communication other than the lower 2 bytes occurs after the first 2 bytes are sent, the Permanent Fail Clear command fails.
