Datasheet, Volume 2

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. 

There is no assurance of atomicity of software read-clear and hardware read-modify-

write; thus, there is a small chance of misreporting.
