Fast Startup
The SAM3S allows the processor to restart in a few microseconds while the processor is in wait
mode or in sleep mode. A fast start up can occur upon detection of a low level on one of the 19
wake-up inputs (WKUP0 to 15 + SM + RTC + RTT).
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 MHz Fast RC oscillator, switches the master
clock on this 4MHz clock and reenables the processor clock.
