When GICD_IERRR bit set ?

Hi,

I am using GIC600. I found one unusal thing related GICD_IERRR bit. During bootup sometime i saw GICD_IERRR bit is set. I am checking all GICD_IERRR bit before configuring distributor, CPU interface and redistributor.GICD_IERRR bit indicate SPI RAM error only or it indicate different error also?

Thank you in advance for your time and support
