SRIX4K commands

30/47
Pcall16() command
Command code = 06h - 04h
The SRIX4K must be in Inventory state to interpret the Pcall16() command.
On receiving the Pcall16() command, the SRIX4K 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 (1111
Initiate() command is issued, or until the SRIX4K is powered off. The new Chip_slot_number
value is then compared with the value 0000
value. If not, the SRIX4K 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 SRIX4K device in Inventory
state present in the reader field range.
