+;Description:
-<code>DELAY <var>x</var></code>
+The cycle counter ''t'' is initialized with 0 and incremented by 1 after each evaluation cycle. The cycle counter is reset, if the input <var>RS</var> is set to a value greater than <code>0</code>. The input <var>RS</var> is checked each time the SPU is started.
