8.5.2.2.1.4 DF Checksum (0x0004)
This function is only available when the bq33100 is in unsealed mode, indicated by the [SS] OperationStatus
flag. A write to this command forces the bq33100 to generate a checksum of the full Data Flash (DF) array. The
generated checksum is then returned within 45 ms.
NOTE
If another SMBus command is received while the checksum is being generated, the DF
Checksum is generated but the response may time out.
