5.2 Invalid Mode Transitions

The firmware of the products covers many invalid transitions and potential issues. The error IRQ and a specific error code indicate all those invalid transitions and potential issues. During the development phase, not all possible scenarios are known, and there can be scenarios that are not valid but not indicated by an event. Therefore, ensure suitable implementation of all the functions. Known actions that will not lead to an error IRQ and an error code entry are:

  • Mode transition from Polling mode to RX mode
  • Antenna tuning without signal at the antenna tuning pin
