7.8 Extended Data Commands
Extended commands offer additional functionality beyond the standard set of commands. They are used in the
same manner; however unlike standard commands, extended commands are not limited to 2-byte words. The
number of command bytes for a given extended command ranges in size from single to multiple bytes, as
specified in Table 10. For details on the SEALED and UNSEALED states, see the Access Modes section in the
bq27742-G1 Technical Reference Manual (SLUUAX0).

(1) SEALED and UNSEALED states are entered via commands to Control() 0x00 and 0x01
(2) In SEALED mode, data flash cannot be accessed through commands 0x3E and 0x3F.
(3) The BlockData() command area shares functionality for accessing general data flash and for using Authentication. See Authentication in
the bq27742-G1 Technical Reference Manual (SLUUAX0) for more details.
