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 19. For details on the SEALED and UNSEALED states, refer to the section entitled Access
Modes.
