INITIATE() Command
Command Code = 06h - 00h
INITIATE() is used to initiate the anti-collision se-
quence of the SRI4K. On receiving the INITIATE()
command, all SRI4K 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
SRI4K in READY state is present in the reader
field range. It speeds up the Chip_ID search pro-
cess. The CHIP_SLOT_NUMBER is not used dur-
ing INITIATE() command access.
