-/*  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.
