2.19.10 PCU_MMIO_FREQ_CLIPPING_CAUSE_LOG Register
This register is the log of the frequency clipping cause in MMIO for both Power plane 0
(IA) and Power plane 1 (GT). The bit definitions are the same as in
PCU_MMIO_FREQ_CLIPPING_CAUSE_STATUS register; the processor will constantly
‘or’ in the status to give a log of any clipping since the last clear. Software can clear the
log by writing zeros to this register.

Note:
There is no assurance of atomicity of software read-clear and hardware read-modify-
write; thus, there is a small chance of misreporting.
