MSMON_CAPT_EVNT MPAM Capture Event Generation Register The power domain of MSMON_CAPT_EVNT is IMPLEMENTATION DEFINED when FEAT_MPAM_MSC_MSMON is implemented and MPAMF_MSMON_IDR.HAS_LOCAL_CAPT_EVNT == '1' MPAM MPAMF_BASE_s 0x0808 MSMON_CAPT_EVNT_s When FEAT_MPAMv1p0 is implemented or FEAT_MPAMv0p1 is implemented WO/RAZ MPAM MPAMF_BASE_ns 0x0808 MSMON_CAPT_EVNT_ns When FEAT_MPAMv1p0 is implemented or FEAT_MPAMv0p1 is implemented WO/RAZ MPAM MPAMF_BASE_rt 0x0808 MSMON_CAPT_EVNT_rt When FEAT_RME is implemented and (FEAT_MPAMv1p0 is implemented or FEAT_MPAMv0p1 is implemented) WO/RAZ MPAM MPAMF_BASE_rl 0x0808 MSMON_CAPT_EVNT_rl When FEAT_RME is implemented and (FEAT_MPAMv1p0 is implemented or FEAT_MPAMv0p1 is implemented) WO/RAZ Generates a local capture event when written with bit[0] as 1. MPAM If FEAT_MPAMv0p1 or FEAT_MPAMv1p0 is implemented, then the following statements apply: MSMON_CAPT_EVNT_s generates local capture events for Secure monitor instances only or for Secure and Non-secure monitor instances. MSMON_CAPT_EVNT_ns generates local capture events for Non-secure monitor instances only. If FEAT_RME is implemented, then the following statements also apply: MSMON_CAPT_EVNT_rt generates local capture events for Root monitor instances only or for Root, Secure, Realm, and Non-secure monitor instances. MSMON_CAPT_EVNT_rl generates local capture events for Realm monitor instances or for for Realm monitor instances or Realm and Non-secure monitor instances. The power and reset domain of each MSC component is specific to that component. MSMON_CAPT_EVNT is a 32-bit register. 31 2 31:2 Reserved, RES0. ALL 1 1 1 In the Secure instance of this register: If ALL is 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 ALL is 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 field is RAZ/WI. In the Root instance of this register: If ALL is written as 1 and NOW is also written as 1, signal a capture event to Root, Realm, Secure, and Non-secure monitor instances in this MSC that are configured with CAPT_EVNT = 7. If ALL is written as 0 and NOW is written as 1, signal a capture event to Root monitor instances within this MSC that are configured with CAPT_EVNT = 7. In the Realm instance of this register: If ALL is written as 1 and NOW is also written as 1, signal a capture event to Realm and Non-secure monitor instances in this MSC that are configured with CAPT_EVNT = 7. If ALL is written as 0 and NOW is written as 1, signal a capture event to Realm monitor instances within this MSC that are configured with CAPT_EVNT = 7. This bit always reads as zero. 0b0 Send capture event only to monitor instances in the same MPAM feature page as this register. 0b1 Send capture event to monitor instances in certain MPAM feature pages as described in the ALL field of this register. NOW 0 0 0 When written as 1, this bit causes an event to those monitor instances described in the ALL field that have 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. 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_CAPT_EVNT_s must only be accessible from the Secure MPAM feature page. MSMON_CAPT_EVNT_ns must only be accessible from the Non-secure MPAM feature page. MSMON_CAPT_EVNT_s and MSMON_CAPT_EVNT_ns must be separate registers. The Secure instance (MSMON_CAPT_EVNT_s) can generate local capture events for Secure monitor instances only or for Secure and Non-secure monitor instances, and the Non-secure instance (MSMON_CAPT_EVNT_ns) can generate local capture events for Non-secure monitor instances only. 2026-03-26 20:27:25 2026-03_rel
