MSMON_CAPT_EVNT, MPAM Capture Event Generation Register

The MSMON_CAPT_EVNT characteristics are:

Purpose

MSMON_CAPT_EVNT is a 32-bit read-write register that generates a local capture event when written with bit 0 as 1.

Configuration

The power domain of MSMON_CAPT_EVNT is IMPLEMENTATION DEFINED.

This register is present only when MPAMF_IDR.HAS_MSMON == 1 and MPAMF_MSMON_IDR.HAS_LOCAL_CAPT_EVNT == 1. Otherwise, direct accesses to MSMON_CAPT_EVNT are IMPLEMENTATION DEFINED.

Attributes

MSMON_CAPT_EVNT is a 32-bit register.

Field descriptions

The MSMON_CAPT_EVNT bit assignments are:

313029282726252423222120191817161514131211109876543210
000000000000000000000000000000ALLNOW

Bits [31:2]

Reserved, RES0.

ALL, bit [1]

In the Secure instance of this register, if ALL written as 1 and NOW is also written as 1, signal a capture event to Secure and Non-secure monitor instances in this MSC that are configured with CAPT_EVNT = 7.

If written as 0 and NOW is written as 1, signal a capture event to Secure monitor instances in this MSC that are configured with CAPT_EVNT = 7.

In the Non-secure instance of this register, this bit is RAZ/WI.

This bit always reads as zero.

ALLMeaning
0b0

Send capture event to Secure monitors only.

0b1

Send capture event to both Secure and Non-secure monitors.

NOW, bit [0]

When written as 1, this bit causes an event to all monitors in this MSC with CAPT_EVNT set to the value of 7.

When this bit is written as 0, no event is signaled.

This bit always reads as zero.

Accessing the MSMON_CAPT_EVNT

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.

MSMON_CAPT_EVNT must be accessible from the Non-secure and Secure address maps.

MSMON_CAPT_EVNT must be banked for the Secure and Non-secure address maps. The Secure instance can generate capture events for both Secure and Non-secure PARTID monitors, and the Non-secure instance can generate capture events for Non-secure PARTID monitors only.

MSMON_CAPT_EVNT can be accessed through the memory-mapped interfaces:

ComponentFrameOffsetInstance
MPAM.anyMPAMF_BASE_s0x0808MSMON_CAPT_EVNT_s

Access on this interface is RW.

ComponentFrameOffsetInstance
MPAM.anyMPAMF_BASE_ns0x0808MSMON_CAPT_EVNT_ns

Access on this interface is RW.
