SRI4K
PCALL16() Command
Command Code = 06h - 04h
The SRI4K must be in INVENTORY state to inter-
pret the PCALL16() command.
On receiving the PCALL16() command, the SRI4K

CHIP_SLOT_NUMBER value (in the 4 least signif-
icant bits of the Chip_ID). CHIP_SLOT_NUMBER
can take on a value between 0 an 15 (1111
value is retained until a new PCALL16() or INI-

match, the SRI4K returns its Chip_ID value. If not,
the SRI4K 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 SRI4K device in INVENTORY state
present in the reader field range.
