AMCIDR1 | Jon's Arm Reference

Provides information to identify an activity monitors component.

For more information, see 'About the Component identification scheme'.

Configuration

It is IMPLEMENTATION DEFINED whether AMCIDR1 is implemented in the Core power domain or in the Debug power domain.

This register is present only when FEAT_AMUv1 is implemented and an implementation implements AMCIDR1. Otherwise, direct accesses to AMCIDR1 are RES0.

Attributes

Field descriptions

Bits [31:8]:

CLASS, bits [7:4]:

Component class.

CLASS	Meaning
0b1001	CoreSight component.

Other values are defined by the CoreSight Architecture.

This field reads as 0x9.

Access to this field is RO.

Access Instructions

Accesses to this register use the following encodings:

Accessible at offset 0xFF4 from AMU

When boolean IMPLEMENTATION_DEFINED "AMU CoreSight management registers ignore access controls", accesses to this register are RO.
When FEAT_RME is implemented, FEAT_AMU_EXTACR is implemented, an access is Secure, and AMROOTCR.RA IN {0b01, 0b00}, accesses to this register are RAZ/WI.
When FEAT_RME is implemented, FEAT_AMU_EXTACR is implemented, an access is Realm, and AMROOTCR.RA IN {0b10, 0b00}, accesses to this register are RAZ/WI.
When FEAT_RME is implemented, FEAT_AMU_EXTACR is implemented, an access is Non-secure, and AMROOTCR.RA != 0b11, accesses to this register are RAZ/WI.
When FEAT_RME is not implemented, FEAT_AMU_EXTACR is implemented, an access is Non-secure, and AMSCR.NSRA == 0, accesses to this register are RAZ/WI.
Otherwise, accesses to this register are RO.
