DACR_D_Msk_

#define DACR_D_Msk_

(

)

(3UL << DACR_D_Pos_(n))

DACR: Dn Mask.

Get the bit mask for domain n access permission.

Example:

// clear access permission for domain 7
__set_DACR(__get_DACR() & ~DACR_D_Msk_(7));

DACR_D_Pos_

#define DACR_D_Pos_

(

n

)

(2U*n)

DACR: Dn Position.

Get the bit position for domain n access permission.

Example:

// retrieve access permission for domain 5
uint32_t domain5 = (__get_DACR() & DACR_D_Msk_(5)) >> DACR_D_Pos_(5);
