11.8.5 Component Identification Registers
There are four read-only Component Identification Registers, Component ID0 through
Component ID3. Table 11-21 shows these registers.
The Component Identification Registers identify Debug as an ARM Debug Interface v5
component. The Component ID registers are:
• Component Identification Register 0.
• Component Identification Register 1 on page 11-33.
• Component Identification Register 2 on page 11-33.
• Component Identification Register 3 on page 11-34.
Component Identification Register 0
The EDCIDR0 characteristics are:
Purpose Provides information to identify an external debug component.
Usage constraints This register is accessible as follows:
Table 11-1 on page 11-5 describes the condition codes.
Configurations The EDCIDR0 is in the Debug power domain.
Attributes See the register summary in Table 11-11 on page 11-21.
Figure 11-16 shows the EDCIDR0 bit assignments.
