The AMS register set adapts the PS SYSMON core to the PS environment. The core's pins are attached to register bits in the AMS register set. Also, the monitor alarms are processed by the AMS interrupt registers to generate the IRQ 88 system interrupt. The AMS registers are located at 0xFFA5_0000.

Access to the AMS register set requires the following.

Privilege from the XPPU protection unit.

VCC_PSINTLP, VCC_PSAUX.

AMS.MON_STATUS [jtag_locked] bit (good AMS_REF_CLK from PS).
