Created page with "Category:Kernel interrupt events class KCacheMaintenanceInterruptEvent extends KBaseInterruptEvent This object handles data cache (L2C ''not'' included) and instr..."

New page

[[Category:Kernel interrupt events]]
class [[KCacheMaintenanceInterruptEvent]] extends [[KBaseInterruptEvent]]

This object handles data cache (L2C ''not'' included) and instruction cache maintainance.

There is only one instance of this object.

Size : 0x4C bytes (N3DS) / 0x34 bytes (O3DS)
