-/* timer.c
- *
- * This file manages the benchmark timer used by the RTEMS Timing Test
- * Suite. Each measured time period is demarcated by calls to
- * Timer_initialize() and Read_timer(). Read_timer() usually returns
- * the number of microseconds since Timer_initialize() exitted.
- *
- * NOTE: It is important that the timer start/stop overhead be
- * determined when porting or modifying this code.

- * To reduce overhead this is best to be the "rawest" hardware interupt
