Memory Base Address (MBAR) – Offset 10 - 001 - ID:795262 | Intel® Core™ Ultra Processors for H-series and U-series Platforms IOE-P I/O Registers

Bit Range	Default	Access	Field Name and Description
63:16	0h	RW	Base Address (BA) Bits (63:16) correspond to memory address signals (63:16), respectively. This gives 64 KB of relocatable memory space aligned to 64 KB boundaries.
15:4	0h	RO	Reserved
3	0h	RO	Prefetchable Indication (PREFETCHABLE) This bit is hardwired to 0 indicating that this range should not be prefetched.
2:1	2h	RO	Type Indication (MBAR_TYPE) If this field is hardwired to 00 it indicates that this range can be mapped anywhere within 32-bit address space. If this field is hardwired to 10 it indicates that this range can be mapped anywhere within 64-bit address space.
0	0h	RO	Resource Type Indicator (RTE) This bit is hardwired to 0 indicating that the base address field in this register maps to memory space
