--
-- This RTEMS task initializes the application.

-- DESCRIPTION:
--
-- This RTEMS task invokes CHECK_READ_TIMER before demonstrating
-- that increasing the order of magnitude of the number of loop
-- iterations performed has a corresponding impact on the time
-- reported by the timer driver.

-- DESCRIPTION:
--
-- This subprogram is used to determine the overhead associated
-- with starting and stopping the timer. It is also useful
-- for determining if unexpected times will be reported.
