Advanced <strong>Protocol</strong> Mode (command is not available for HITAG 1 transponders based on ASIC<br />
HT1 ICS30 01x ; only available for HITAG 1 transponders based on ASIC HT1 ICS30 02x).<br />
For further information on the Advanced <strong>Protocol</strong> Mode see chapter „Transponders“.<br />

7 0 ------ 31 24<br />
n+2 Status SNR-LSB ------ SNR-MSB more BCC<br />
n = 0 if an error occurred (error code in Status).<br />
n = 5 if data were read from a transponder (Status = 0).<br />
more: Proximity Reader: more is always 0.<br />
Long Range Reader: more equal to one indicates that there is at least one additional<br />
transponder in the reading area of the read/write device.<br />
