# SCFG_SetIntcExpanded

## Syntax

      #include <twl/scfg.h>

      static inline void SCFG_SetIntcExpanded( BOOL sw );

## Arguments

`sw` | Determines if the ARM9 INTC circuit is extended from the NITRO-CPU. If `TRUE`, extensions are used. If `FALSE`, the circuit will be identical to NITRO's INTC circuit.

## Return Values

None.

## Description

Configures the use of extensions for the ARM9 interrupt controller (INTC) circuit.

Extensions will be used in TWL mode by default.

Note: Use this function when running on TWL hardware.

Because NITRO hardware does not include an SCFG block, this function is not expected to be invoked on NITRO hardware.
