/* address declaration */

#define io_P2 (*(volatile unsigned short *) 0x00800200)

/* access to each bit (write 0 to extra bit) */

#define SET_P2_B5(x) (io_P2=(io_P2 & 0x03DF)|(x)<<5)

#define SET_P2_B8(x) (io_P2=(io_P2 & 0x02FF)|(x)<<8)

/* example function for accessing bit field with macro */

/* write 0 to bit No. 8 */

SET_P2_B8(0);

/* write 0 to bit No. 5 */

SET_P2_B5(0);

CC32R does not generate a code for accessing the bit field with a specific size (half-word, etc.). It automatically accesses the bit

field with the minimum size.
