The SAM3U allows the processor to restart in a few microseconds while the processor is in wait
mode. A fast start up can occur upon detection of a low level on one of the 19 wake-up inputs.
The fast restart circuitry, as shown in
up signal to the Power Management Controller. As soon as the fast start-up signal is asserted,
the PMC automatically restarts the embedded 4/8/12 MHz fast RC oscillator, switches the mas-
ter clock on this 4/8/12 MHz clock and reenables the processor clock.
