9.9 Operating mode "WRITE DATA”
In the “WRITE DATA” operating mode more than 28 bytes can be written to an ID tag with a write
operation. The data is sequentially transferred from the controller to the device.
Transferring data from the controller to the device:
u The controller sets the command value ”0x07”, the address (16bits) and the data length (16bits) in
the process data output image. To identify the ID tag, the EPC and its length are also necessary.
For the memory bank, only the value USER: “0x03” can be specified.
u The controller starts the write operation with the status bit “Cmd Start”.
w The device acknowledges the start of the write operation by setting the status bit ”Cmd Start
Acknowledge” in the process data input image.
u The controller fills the data in the process data output image (data 0 to 27) and increases the block
counter by “1”.
w The device acknowledges receipt of the data by increasing the block counter in the process
data output image by 1.
u The two previous steps are repeated until all data has been transferred.
w The device sets the status bit “Cmd End” with the last transfer.
u The write operation is terminated.
If the operation was unsuccessful, the device sets the error value and the status bit "Cmd End"
in the process image. Data transfer is interrupted.
