SRIX4K commands
SRIX4K
32/47
9.4
Select(Chip_ID) command
Command code = 0Eh
The Select() command allows the SRIX4K to enter the Selected state. Until this command is
issued, the SRIX4K will not accept any other command, except for Initiate(), Pcall16() and
Slot_marker(). The Select() command returns the 8 bits of the Chip_ID value. An SRIX4K in
Selected state, that receives a Select() command with a Chip_ID that does not match its
own is automatically switched to Deselected state.
Figure 33.
Select request format
Request parameter:
8-bit Chip_ID stored during the anticollision sequence
Figure 34.
Select response format
Response parameters:
Chip_ID of the selected tag. Must be equal to the transmitted Chip_ID
