Configuration signals

Table A.3 shows the configuration signals.

Table A.3. Configuration signals

Signal	Direction	Description
AA64nAA32[CN:0]	Input	Register width state: 0 AArch32. 1 AArch64. This pin is sampled only during reset of the processor.
CFGEND[CN:0]	Input	Endianness configuration at reset. It sets the initial value of the EE bits in the CP15 SCTLR_EL3 and SCTR_S registers: 0 EE bit is LOW. 1 EE bit is HIGH. This pin is sampled only during reset of the processor.
CFGTE[CN:0]	Input	Enable T32 exceptions. It sets the initial value of the TE bit in the CP15 SCTLR register: 0 TE bit is LOW. 1 TE bit is HIGH. This pin is sampled only during reset of the processor.
CLUSTERIDAFF1[7:0]	Input	Value read in the Cluster ID Affinity Level 1 field, MPIDR bits[15:8], of the CP15 MPIDR register. These pins are sampled only during reset of the processor.
CLUSTERIDAFF2[7:0]	Input	Value read in the Cluster ID Affinity Level 2 field, MPIDR bits[23:16], of the CP15 MPIDR register. These pins are sampled only during reset of the processor.
CP15SDISABLE[CN:0]	Input	Disable write access to some secure CP15 registers.
CRYPTODISABLE[CN:0]	Input	Disables the Cryptography Extensions. This pin is sampled only during reset of the processor.
RVBARADDRx[39:2]	Input	Reset Vector Base Address for executing in 64-bit state. These pins are sampled only during reset of the processor.
VINITHI[CN:0]	Input	Location of the exception vectors at reset. It sets the initial value of the V bit in the CP15 SCTLR register: 0 Exception vectors start at address 0x00000000. 1 Exception vectors start at address 0xFFFF0000. This pin is sampled only during reset of the processor.
