Long Commands
After each POR or global reset command, the start state becomes active. In this state, ATA5590
reads the trigger configuration out of the EEPROM. If the trigger function is enabled (trigger con-
figuration(1)), the second bit is read out to configure the sub-carrier frequency.
Table 5-1.
The sub-carrier modulates the field as long as the tag does not receive a notch tick. After detec-
tion of the start of the forward stream, the trigger function is switched off.
The trigger function becomes active again after receiving a global reset command.
The trigger function can be controlled by a special programming sequence.
ATA5590 supports long and short commands.
