Dcache Parity Error Status Register (DC_PERR_STAT)
Address: IPR Mbox, Index=212
The Dcache parity error status (DC_PERR_STAT) register is a read/write register. If a Dcache parity error occurs while the DC_PERR_STAT is unlocked, the error status is loaded into <05:02>. The lock bit is set and the register is locked against further updates (except for the SEO bit) until software writes a 1 to clear the lock bit.
