REGISTER 3: DOMAIN ACCESS CONTROL REGISTER
Register 3 is the read/write domain access control register consisting of sixteen 2-bit fields. Each of these 2-bit fields
defines the access permissions for the domains shown in Table 2-13.
The encoding of the two bit domain access permission field is given in Table 3-5 on page 3-19. The following
instructions can be used to access the domain access control register:
MRC p15, 0, Rd, c3, c0, 0; read domain 15:0 access permissions
MCR p15, 0, Rd, c3, c0, 0; write domain 15:0 access permissions
