# 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:

31 | 30 | 29 | 28 | 27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0
RES0 | ALL | NOW

#### 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.

ALL | Meaning
--- | ---
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:

Component | Frame | Offset | Instance
--- | --- | --- | ---
MPAM.any | MPAMF_BASE_s | 0x0808 | MSMON_CAPT_EVNT_s

Access on this interface is RW.

Component | Frame | Offset | Instance
--- | --- | --- | ---
MPAM.any | MPAMF_BASE_ns | 0x0808 | MSMON_CAPT_EVNT_ns

Access on this interface is RW.
