-/*
-* The mbed lpc1768 does not support the deepsleep mode
-* as a debugger is connected to it (the mbed interface).
-*
-* As mentionned in an application note from NXP:
-*
-*       http://www.po-star.com/public/uploads/20120319123122_141.pdf
-*
-*       {{{
-*       The user should be aware of certain limitations during debugging.
-*       The most important is that, due to limitations of the Cortex-M3
-*       integration, the LPC17xx cannot wake up in the usual manner from
-*       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().
