8.5.7 Command: Get data from buffer (Continuous mode)
NOTE
The command code for fast processing with the loop counter is 0x2011 (hex.) or
8209 (dec.).
The Get data from buffer command (Continuous mode) passes on data stored in the interface
to the controller. The command is required to transfer read data to the controller in Continuous
mode or in Continuous presence sensing mode. The data is transferred to the controller in frag-
ments of up to 128 bytes. The size of the fragments can be set by the user. An EPC is not di-
vided by fragment limits. If an EPC does not fit completely in a fragment, it is automatically
moved to the next fragment.
NOTE
The Get data from buffer command does not end Continuous mode.
