Radio Timeslot signals

Signals come from the peripherals and arrive within a Radio Timeslot.

Signals are received in a signal handler callback function that the application must provide. The signal handler runs in interrupt priority level 0, which is the highest priority in the system, see section Interrupt priority levels.
