Anti-collision Timing
List of ATA5558 Supported Commands
The first two bits of any interrogator command are called Start Of Command (SOC) and are
always 00. This pulse interval is used for auto calibration purposes. The following series of dual
bit packets define the interrogator command opcodes and the command dependant parameter
information. A command overview is given in
SOC
