11.7.13 Performance Monitors Component Identification Registers

There are four read-only Performance Monitors Component Identification Registers, Performance Monitors Component ID0 through Performance Monitors Component ID3. The following table shows these registers.

Table 11-19 Summary of the Performance Monitors Component Identification Registers

Register Value Offset
PMCIDR0 0x0D 0xFF0
PMCIDR1 0x90 0xFF4
PMCIDR2 0x05 0xFF8
PMCIDR3 0xB1 0xFFC
The Performance Monitors Component Identification Registers identify Performance Monitors as ARM PMUv3 architecture. The Component ID registers are:

Performance Monitors Component Identification Register 0

The PMCIDR0 characteristics are:

Purpose
