SYS_POW_A72 24-bit representation of the instantaneous power consumption of the Cortex-A72 cluster:
•
The value of these bits represents [SYS_I_A72(I) × SYS_V_A72(V)]/617402 watts.
•
Measured power consumption=[SYS_POW_A72]/617402 watts.
•
The
CB_nRST
reset signal resets the register to zero. The register then updates every 100µs after the
reset.
