Description

The CPACR controls access to coprocessors CP0 to CP13.

The CPACR characteristics are:

Bits	Name	Function
[31]	ASEDIS	Disable Advanced SIMD functionality.
[30]	D32DIS	Disable use of D16-D31 of the Floating-point Extension register file.
[29]	-	Reserved.
[28]	TRCDIS	Disable CP14 access to trace registers.
[27:26]	CP13	Access rights for coprocessor 13.
[25:24]	CP12	Access rights for coprocessor 12.
[23:22]	CP11	Access rights for coprocessor 11.
[21:20]	CP10	Access rights for coprocessor 10.
[19:18]	CP9	Access rights for coprocessor 9.
[17:16]	CP8	Access rights for coprocessor 8.
[15:14]	CP7	Access rights for coprocessor 7.
[13:12]	CP6	Access rights for coprocessor 6.
[11:10]	CP5	Access rights for coprocessor 5.
[9:8]	CP4	Access rights for coprocessor 4.
[7:6]	CP3	Access rights for coprocessor 3.
[5:4]	CP2	Access rights for coprocessor 2.
[3:2]	CP1	Access rights for coprocessor 1.
[1:0]	CP0	Access rights for coprocessor 0.

Consider __get_CPACR and __set_CPACR to access this register.
