RESET_TO_INVENTORY() Command
Command Code = 0Ch
On receiving the RESET_TO_INVENTORY()
command, all SRI4K devices in SELECTED state
revert to INVENTORY state. The concerned
SRI4K devices are thus resubmitted to the anti-
collision sequence. This command is useful when
two SRI4K devices with the same 8-bit Chip_ID
happen to be in SELECTED state at the same

time. Forcing them to go through the anti-collision
sequence again allows the reader to generates
new PCALL16() commands and so, to set new
random Chip_IDs.
The RESET_TO_INVENTORY() command does
not generate a response.
All SRI4K devices that are not in SELECTED state
ignore the RESET_TO_INVENTORY() command.
