8.5.6 Command: Continuous mode
In Continuous mode, a user-defined command is sent to the read/write head and saved in the
read/write head. The commands write, read and inventory can be executed in Continuous
mode. The parameters for Continuous mode must be set directly in the read/write head.
The command is continuously executed until the user terminates Continuous mode. Continu-
ous mode can be terminated with a reset command.
NOTE
The reset command resets all read data.
Read/write heads in Continuous mode send all command related data to the interface. The
data is stored in the FIFO memory of the interface and can be queried by the controller via the
Get Data from FIFO command.
Commands in Continuous mode are triggered if the read/write head detects a tag. If there is a
tag in the detection range of the read/write head, the command sent in Continuous mode is
executed with the next tag.
NOTE
In Continuous mode the Tag in detection range signal is not updated.
Start address and length cannot be changed during the execution of Continuous
mode.
After Continuous mode is restarted, all data of the already running Continuous
mode is deleted.
