Table 8-3.
Note:
Table 8-4.
Table 8-5.
After getting the length definition out of the header section, the tag receives a 6-bit command
and 2-bit CRC information. If this CRC check passes, the tag expects the EOT field.
As no parameter field follows the short commands, the modulation properties are defined by bits
(3:2) of the command frame. The CRC is stored in bits 1 and 0 of the frame.

If there is a need in the application for using such commands several times, there is the possibility
of shortening the whole procedure by using the short temporary command repeat_arb
