Figure 4.2.3 Kernel Mode Address Space
Note 1: In 32-bit mode, bit 31 is sign-extended through bits 63-32. Failure results in an address error
exception.
Note 2: 0xff00_0000 through 0xff3f_ffff in 32-bit mode and 0xffff_ffff_ff00_0000 through 0xffff_ffff_ff3f_ffff in
64-bit mode are reserved (unmapped, uncached) for use by registers in the Debug Support Unit
and the processor’s peripherals.
