5.2.5 Set Module Idle
Function: set the module idle. In idle mode, the module of RF output turn to OFF, PCD
power down, and CPU in idle mode, so the power consumption reduces to about 100uA. Sending
the next command to module will wake up the module, and then the RF output ON and automatic
detecting card restore the settings. The module will enter into idle mode after the answer
procedure is finished for this command. In I²C and SPI mode, host needs to get the answer, and
then the module goes into idle mode. The module with USB interface doesn't support idle mode.
