-/* Timer_init()
- *
- * This routine initializes the Z8536 timer on the SQSIO4 SQUALL
- * board for the CVME961 board. The timer is setup to provide a
- * tick every 1 millisecond.
- *
- * Input parameters: NONE
- *
- * Output parameters: NONE
- *
- * NOTE: This routine will not work if the optimizer is enabled
- * for most compilers. The multiple writes to the Z8536
- * will be optimized away.
- *
- * It is important that the timer start/stop overhead be
- * determined when porting or modifying this code.
