20<P>None.</P>
21<H2>Return Values</H2>
22<P>The operating speed configured for the ARM9 CPU.<BR><CODE>SCFG_CPU_SPEED_1X</CODE>: 67.03 MHz (equal to NITRO) <BR><CODE>SCFG_CPU_SPEED_2X</CODE>: 134.06 MHz (double NITRO's speed)</P>
23<H2>Description</H2>
24<P>Gets the current frequency configured for the ARM9-CPU.</P>
25<P>Although only TWL hardware has an SCFG block, this function returns the correct value (<CODE>SCFG_CPU_SPEED_1X</CODE>) even if executed on NITRO hardware.</P>
