# SCFG_GetCpuSpeed

## Syntax

      #include <twl/scfg.h>

      static inline SCFGCpuSpeed SCFG_GetCpuSpeed( void );

## Arguments

None.

## Return Values

The operating speed configured for the ARM9 CPU.
`SCFG_CPU_SPEED_1X`: 67.03 MHz (equal to NITRO)
`SCFG_CPU_SPEED_2X`: 134.06 MHz (double NITRO's speed)

## Description

Gets the current frequency configured for the ARM9-CPU.

Although only TWL hardware has an SCFG block, this function returns the correct value (`SCFG_CPU_SPEED_1X`) even if executed on NITRO hardware.
