SRI4K commands

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 anticollision
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 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 SRI4K devices that are not in Selected state ignore the Reset_to_inventory() command.
