RESET_TO_INVENTORY() command

Command Code = 0Ch

On receiving the RESET_TO_INVENTORY() command, all SRIX4K devices in SELECTED

state revert to INVENTORY state. The concerned SRIX4K devices are thus resubmitted to

the anticollision sequence. This command is useful when two SRIX4K devices with the

same 8-bit Chip_ID happen to be in SELECTED state at the same time. Forcing them to go

through the anticollision 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 SRIX4K devices that are not in SELECTED state ignore the RESET_TO_INVENTORY()

command.
