12.5. AArch32 PMU register summary

The PMU counters and their associated control registers are accessible in the AArch32 Execution state from the internal CP15 system register interface with MCR and MRC instructions for 32-bit registers and MCRR and MRRC for 64-bit registers.

Table 12.9 gives a summary of the Cortex-A53 PMU registers in the AArch32 Execution state. For those registers not described in this chapter, see the Arm® Architecture Reference Manual Armv8, for Armv8-A architecture profile.

See the Memory-mapped register summary for a complete list of registers that are accessible from the internal memory-mapped interface or the external debug interface.
