MPAMF_SIDR, MPAM Features Secure Identification Register

The MPAMF_SIDR characteristics are:

Purpose

The MPAMF_SIDR is a 32-bit read-only register that indicates the maximum Secure PARTID and Secure PMG on this MSC.

Configuration

The power domain of MPAMF_SIDR is IMPLEMENTATION DEFINED.

Attributes

MPAMF_SIDR is a 32-bit register.

Field descriptions

The MPAMF_SIDR bit assignments are:

313029282726252423222120191817161514131211109876543210
RES0S_PMG_MAXS_PARTID_MAX

Bits [31:24]

Reserved, RES0.

S_PMG_MAX, bits [23:16]

Maximum value of Secure PMG supported by this component.

S_PARTID_MAX, bits [15:0]

Maximum value of Secure PARTID supported by this component.

Accessing the MPAMF_SIDR

This register is part of the MPAMF_BASE memory frame. In a system that supports Secure and Non-secure memory maps, the MPAMF_BASE frame must be accessible in both Secure and Non-secure memory address maps.

MPAMF_SIDR must only be accessible from the Secure address map. If the system or the MSC does not support the Secure address map, this register must not be accessible.

MPAMF_SIDR can be accessed through the memory-mapped interfaces:

ComponentFrameOffsetInstance
MPAM.anyMPAMF_BASE_s0x0008MPAMF_SIDR_s

Access on this interface is RO.
