Reserved RSVD 0x6b...0x7f N/A R R

DesignCapacity( ): 0x3c/0x3d

SEALED and UNSEALED Access: This command returns the value is stored in Design Capacity and is

expressed in mAh. This is intended to be the theoretical or nominal capacity of a new pack, but has no bearing

on the operation of the fuel gauge functionality

DataFlashClass( ): 0x3e

UNSEALED Access: This command sets the data flash class to be accessed. The class to be accessed should

be entered in hexadecimal.

SEALED Access: This command is not available in SEALED mode.

DataFlashBlock( ): 0x3f

UNSEALED Access: This command sets the data flash block to be accessed. When 0x00 is written to

BlockDataControl( ), DataFlashBlock( ) holds the block number of the data flash to be read or written. Example:

writing a 0x00 to DataFlashBlock( ) specifies access to the first 32 byte block and a 0x01 specifies access to the

second 32 byte block, and so on.

SEALED Access: This command directs which data flash block will be accessed by the BlockData( ) command.

Writing a 0x01 or 0x02 to DataFlashBlock( ) specifies the BlockData( ) command will transfer Manufacturer Info

Block A or B, respectively.

BlockData( ): 0x40…0x5f

UNSEALED Access: This data block is the remainder of the 32 byte data block when accessing data flash.

SEALED Access: This data block is the remainder of the 32 byte data block when accessing Manufacturer

Block Info A or B.

BlockDataChecksum( ): 0x60

UNSEALED Access: This byte contains the checksum on the 32 bytes of block data read or written to data flash.

The least-significant byte of the sum of the data bytes written must be complemented ( [255 – x] , for x the

least-significant byte) before being written to 0x60.

SEALED Access: This byte contains the checksum for the 32 bytes of block data written to Manufacturer Info

Block A or B. The least-significant byte of the sum of the data bytes written must be complemented ( [255 – x] ,

for x the least-significant byte) before being written to 0x60.

BlockDataControl( ): 0x61

UNSEALED Access: This command is used to control data flash access mode. Writing 0x00 to this command

enables BlockData( ) to access general data flash. Writing a 0x01 to this command enables SEALED mode

operation of DataFlashBlock( ).

SEALED Access: This command is not available in SEALED mode.

DeviceNameLength( ): 0x62

UNSEALED and SEALED Access: This byte contains the length of the Device Name.

DeviceName( ): 0x63…0x69

UNSEALED and SEALED Access: This block contains the device name that is programmed in Device Name
