The formula is : Frequency(Hz) =
enable: Enables (1) or disables (0) the timer interrupt
time_out_ms: Specifies the time-out interval in milliseconds. The
function returns if the interval elapses, even if the interrupt is non-
signaled. If time_out_ms is zero, the function tests the Di state and
returns immediately. If time_out_ms is -1, the function time-out
interval does not elapse (infinite).
