sahilmgandhi 18:6a4db94011d3 39 * The user should be aware of certain limitations during debugging.
sahilmgandhi 18:6a4db94011d3 40 * The most important is that, due to limitations of the Cortex-M3
sahilmgandhi 18:6a4db94011d3 41 * integration, the LPC17xx cannot wake up in the usual manner from
sahilmgandhi 18:6a4db94011d3 42 * Deep Sleep and Power-down modes. It is recommended not to use these
sahilmgandhi 18:6a4db94011d3 43 * modes during debug. Once an application is downloaded via JTAG/SWD
sahilmgandhi 18:6a4db94011d3 44 * interface, the USB to SWD/JTAG debug adapter (Keil ULINK2 for example)
sahilmgandhi 18:6a4db94011d3 45 * should be removed from the target board, and thereafter, power cycle

sahilmgandhi 18:6a4db94011d3 48 *

sahilmgandhi 18:6a4db94011d3 50 * mbed_interface_disconnect() semihosting call is made, the
sahilmgandhi 18:6a4db94011d3 51 * core cannot wake-up from deepsleep.
