#define CONFIG_MEMORY_MODEL_LARGE

Configuration symbol to enable 24 bit pointers.

#define CONFIG_MEMORY_MODEL_SMALL

Configuration symbol to enable 16 bit pointers.

Note

If no memory model is defined, SMALL is default.

#define CONFIG_MEMORY_MODEL_TINY

Configuration symbol to enable 8 bit pointers.

void ccp_write_io	(	void *	addr,
		uint8_t	value
	)

Write to a CCP-protected 8-bit I/O register.

Parameters

addr	Address of the I/O register
value	Value to be written

Note

Using IAR Embedded workbench, the choice of memory model has an impact on calling convention. The memory model is not visible to the preprocessor, so it must be defined in the Assembler preprocessor directives.
