/* Title: wait
 * Generic wait functions.
 *
 * These provide simple NOP type wait capabilities.
 *
 * Example:
 * > #include "mbed.h"
 * >
 * > DigitalOut heartbeat(LED1);
 * >
 * > int main() {
 * >     while (1) {
 * >         heartbeat = 1;
 * >         wait(0.5);
 * >         heartbeat = 0;
 * >         wait(0.5);
 * >     }
 * > }

 * dynamic power used by the processor, memory systems and buses. The processor, peripheral and 
 * memory state are maintained, and the peripherals continue to work and can generate interrupts.
 * 
 * The processor can be woken up by any internal peripheral interrupt or external pin interrupt.
 * 
 * Note: The mbed interface semihosting is disconnected as part of going to sleep, and can not be restored. 
 * Flash re-programming and the USB serial port will remain active, but the mbed program will no longer be

 * is still maintained. 
 * 
 * The processor can only be woken up by an external interrupt on a pin or a watchdog timer.
