1. The Low power wait mode is entered when executing a WFE instruction in Low power run mode. In WFE mode, the

interrupt is served if it has been previously enabled. After processing the interrupt, the processor goes back to WFE mode.

When the interrupt is configured as a wakeup event, the CPU wakes up and resumes processing.

2. The TLI interrupt is the logic OR between TIM2 overflow interrupt, and TIM4 overflow interrupts.

3. The device is woken up from Halt or Active-halt mode only when the address received matches the interface address.
