bq20z80-V101
SLUS625D – SEPTEMBER 2004 – REVISED OCTOBER 2005
This read/write block (2-words) command allows the user to change the Unseal key for the Sealed-to-Unsealed
security-state transition. This function is only available when the bq20z80 is in the Full-Access mode
(SBS.OperationStatus( ), FAS is clear).
This read/write block (2-words) command allows the user to change the Full-Access security key for the
Unsealed-to-Full-Access security-state transition. This function is only available when the bq20z80 is in the
Full-Access mode (SBS.OperationStatus( ), FAS is clear).
This read/write block (2-words) command allows the user to change the Permanent-Failure-Clear key. This
function is only available when the bq20z80 is in the Full Access mode (SBS.OpertionStatus( ), FA is set).
This read-block function returns the data stored in DF:Manufacturer Info 1...8 (MfgInfo), where byte 1 is the MSB
with a maximum length of 8 data + 1 length byte. When the bq20z80 is in Unsealed or Full Access mode, this
block is R/W.
This write-word command allows the user to change the sense resistor value used, in units of
with a range of
0 to 62535. The bq20z80 automatically updates the respective calibration data on receipt of a new sense resistor
value.
This write word command sets the bq20z80 data flash subclass that is to be accessed by the
SBS.DataFlashSubClass( ) commands that follow. These commands only allow access to the configuration data
flash locations within the respective labeled subclass. See the Data Flash Access section for further details.
A NACK is returned to the SBS.DataFlashClass( ) command if the value of the class is outside of the allowed
range. The subclasses are defined in the Data Flash section of this data sheet.
These commands are used to access the consecutive 32-byte pages of each subclass.
NOTE:
Any DF location deemed Reserved responds with a NACK unless the bq20z80 is in
the correct security state to allow access.
