SRI2K commands

Pcall16() command
Command code = 06h - 04h
The SRI2K must be in Inventory state to interpret the Pcall16() command.
On receiving the Pcall16() command, the SRI2K first generates a new random
Chip_slot_number value (in the 4 least significant bits of the Chip_ID). Chip_slot_number
can take on a value between 0 an 15 (1111b). The value is retained until a new Pcall16() or
Initiate() command is issued, or until the SRI2K is powered off. The new Chip_slot_number
value is then compared with the value 0000b. If they match, the SRI2K returns its Chip_ID
value. If not, the SRI2K does not send any response.
The Pcall16() command, used together with the Slot_marker() command, allows the reader
to search for all the Chip_IDs when there are more than one SRI2K device in Inventory state
present in the reader field range.
