Initiate() command
Command code = 06h - 00h
Initiate() is used to initiate the anticollision sequence of the SRIX4K. On receiving the
Initiate() command, all SRIX4K devices in Ready state switch to Inventory state, set a new
8-bit Chip_ID random value, and return their Chip_ID value. This command is useful when
only one SRIX4K in Ready state is present in the reader field range. It speeds up the
Chip_ID search process. The Chip_slot_number is not used during Initiate() command
access.
