* Deep Sleep and Power-down modes. It is recommended not to use these
* modes during debug. Once an application is downloaded via JTAG/SWD
* interface, the USB to SWD/JTAG debug adapter (Keil ULINK2 for example)
* should be removed from the target board, and thereafter, power cycle
* the LPC17xx to allow wake-up from deep sleep and power-down modes
* }}}
*
* As the interface firmware does not reset the target when a
* mbed_interface_disconnect() semihosting call is made, the
* core cannot wake-up from deepsleep.
*
* We treat a deepsleep() as a normal sleep().
