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

Writing a 0x00 to DataFlashBlock() specifies the BlockData() command will transfer authentication data. Issuing a

0x01, 0x02, or 0x03 instructs the BlockData() command to transfer Manufacturer Info Block A or B,

respectively.

Reading Device Name in SEALED Mode

To read the DeviceName when in SEALED mode, set the DataFlashBlock() (command 0x3F) to 0x05, and read

the device name from the BlockData() commands.

In general, there will be at least 12 null characters because the data flash field is limited to 20 bytes and the

SEALED mode block has 32 bytes of space.

BlockData(): 0x40…0x5F

This command range is used to transfer data for data flash class access. This command range is the 32-byte

data block used to access Manufacturer Info Block A or B. Manufacturer Info Block A is read-only for the

SEALED access. UNSEALED access is read/write.

BlockDataChecksum(): 0x60

The host system should write this value to inform the device that new data is ready for programming into the

specified data flash class and block.

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 8-bit

summation of the BlockData() (0x40 to 0x5F) on a byte-by-byte basis) 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 8-bit summation of the BlockData() (0x40 to 0x5F) on a byte-by-byte basis) before being written to 0x60.

BlockDataControl(): 0x61

UNSEALED Access: This command is used to control data flash ACCESS mode. The value determines the data

flash to be accessed. Writing 0x00 to this command enables BlockData() to access general data flash.

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

Reserved(): 0x62...0x69

Reserved.

BatAlertConfig(): 0x6A/0x6B

The BatAlertConfig() register can be written to set which faults, once detected, will trigger an Alert. The data flash

value for BatAlertConfig() is used to initialize this value.
