Power management and operating modes

3.1 Operating modes
The TG-F321 has 2 operating modes: Idle and Active. In Active mode, the TG-F321 communicates actively with a tag or an external MCU. Idle mode includes two low consumption states: Hibernate and Tag Detector. The TG-F321 can switch from one mode to another.
Table 2. Operating modes

in order to communicate. Low level on liRQ_IN pin is the only wakeup solute.
Tag Detector| Low power consumption, Tag detection. Wakeup solute is configurable:
— Timer
— IRQ_lN pin
— SPI SS pin
— Tag detector
INFO (low-fiequency oscillator) is running in this state.
Active| Standby  or Reader| Main communication mode. HFO (high-fiequency oscillator) is running, TG-F321 is able to decode and execute commands from external MCU. It can switch the reader ON and OFF and communicate with a tag or an external MCU.

Hibernate and Tag-Detector states can only be activated by a command from the external MCU. As soon as Application environment any of these states are activated, the TG-F321 can no longer communicate with the external MCU. It can only be woken up.
The behavior of the TG-F321 in ‘Tag-Detector’ state is defined by the Idle command.
