/*
* 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().
