Field Name | Bits | Type | Reset Value | Description |
ARCHITECT | 31:21 | roRead-only | 0x23B | Defines the architecture of the component. For CTI, this is Arm Limited.Bits [31:28] are the JEP 106 continuation code, 0x4.Bits [27:21] are the JEP 106 ID code, 0x3B. |
PRESENT | 20 | roRead-only | 0x1 | When set to 1, indicates that the DEVARCH is present.This field is 1 in v8-A. |
REVISION | 19:16 | roRead-only | 0x0 | Defines the architecture revision. For architectures defined by Arm this is the minor revision.For CTI, the revision defined by v8-A is 0x0.All other values are reserved. |
ARCHID | 15:0 | roRead-only | 0x1A14 | Defines this part to be a v8-A debug component. For architectures defined by Arm this is further subdivided.For CTI:Bits [15:12] are the architecture version, 0x1.Bits [11:0] are the architecture part number, 0xA14.This corresponds to CTI architecture version CTIv2. |
