+/* Title: mbed_interface
+ * Functions to control the mbed interface
+ *
+ * mbed Microcontrollers have a built-in interface to provide functionality such as 
+ * drag-n-drop download, reset, serial-over-usb, and access to the mbed local file 
+ * system. These functions provide means to control the interface suing semihost
+ * calls it supports.
