# SCFG_SetConfigBlockInaccessible

## Syntax

      #include <twl/scfg.h>

      static inline void SCFG_SetConfigBlockInaccessible( void );

## Arguments

None.

## Return Values

None.

## Description

Prohibits access to the ARM9 configuration block.

Once prohibited, access to the ARM9 configuration block will no longer be possible. In other words, this setting itself (prohibiting access) cannot be undone. This function should therefore be called after configuration is complete for all settings when prohibiting access. However, applications should not normally set this to be inaccessible.

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 called on NITRO hardware.
