Short commands are based on the following fields:
The 8-bit command field contains the 2-bit CRC.
An EOT frame is based on two EOF symbols.
Long commands (read and program) are based on the following fields:
The header, 8-bit command frame, 8-bit parameter frame, 16-bit CRC frame, and EOT frame
are default structures of long read and program commands.
Anticollision and group-selection commands are based on the following structure:
The EOF symbol is used to close the arbitration.
The length and the mechanism included in the CRC field transmitted after the command section
depends on the internal communication status of the tag, and the control sequences transmitted
by the reader during the forward link.
In default mode (no additional action of the reader), the CRC field has a length of 16 bits.
After the tag becomes synchronous to the stream of the reader, the reader can change the bit
count as well as the communication style of the CRC field.
