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.
