The MSMON_OFLOW_MSI_ADDR_H characteristics are:
MSMON_OFLOW_MSI_ADDR_H is a 32-bit read/write register for the high part of the MPAM monitor overflow MSI address.
MSMON_OFLOW_MSI_ADDR_H_s is the high part of the MSI write address for monitor overflow interrupts from Secure monitor instances. MSMON_OFLOW_MSI_ADDR_H_ns is the high part of the MSI write address for monitor overflow interrupts from Non-secure monitor instances.
The power domain of MSMON_OFLOW_MSI_ADDR_H is IMPLEMENTATION DEFINED.
This register is present only when FEAT_MPAMv1p1 is implemented and MPAMF_MSMON_IDR.HAS_OFLW_MSI == 1. Otherwise, direct accesses to MSMON_OFLOW_MSI_ADDR_H are RES0.
MSMON_OFLOW_MSI_ADDR_L, MSMON_OFLOW_MSI_ADDR_H, MSMON_OFLOW_MSI_ATTR, MSMON_OFLOW_MSI_DATA, and MSMON_OFLOW_MSI_MPAM must all be implemented to support MSI writes for monitor overflow interrupts.
The power and reset domain of each MSC component is specific to that component.
MSMON_OFLOW_MSI_ADDR_H is a 32-bit register.

MSI write address bits[51:32].
This register is within the MPAM feature page memory frames. In a system that supports Secure and Non-secure memory maps, there must be both Secure and Non-secure MPAM feature pages.
MSMON_OFLW_MSI_ADDR_H_s must be accessible from the Secure MPAM feature page. MSMON_OFLW_MSI_ADDR_H_ns must be accessible from the Non-secure MPAM feature page.
MSMON_OFLW_MSI_ADDR_H_s and MSMON_OFLW_MSI_ADDR_H_ns must be separate registers. The Secure instance (MSMON_OFLW_MSI_ADDR_H_s) accesses the high part of the monitor overflow MSI write address of Secure monitors, and the Non-secure instance (MSMON_OFLW_MSI_ADDR_H_ns) accesses the high part of the monitor overflow MSI write address of Non-secure monitors.
