+//! Interacting with debugging agent
+//!
+//! # Example
+//!
+//! This example will show how to terminate the QEMU session. The program
+//! should be running under QEMU with semihosting enabled
+//! (use `-semihosting` flag).
+//!
+//! Target program:
+//!
+//! ```no_run
+//! use cortex_m_semihosting::debug::{self, EXIT_SUCCESS, EXIT_FAILURE};
+//!
+//! fn main() {
+//! if 2 == 2 {
+//! // report success
+//! debug::exit(EXIT_SUCCESS);
+//! } else {
+//! // report failure
+//! debug::exit(EXIT_FAILURE);
+//! }
+//! }
+//!
+
+/// This values are taken from section 5.5.2 of
+/// ADS Debug Target Guide (DUI0058).
+// TODO document

+/// or failure. If you need to pass more than one type of error, consider
+/// using `report_exception` syscall instead.
+///
+/// This call should not return. However, it is possible for the debugger

+/// to request that the application continue. In that case this call

+///
+/// * `reason` - A reason code reported back to the debugger.
