The PL SYSMON unit is controlled by the PLSYSMON register set at 0xFFA5_0C00. These registers are also protected by the XPPU and require a valid clock. In addition, the PCAP isolation wall must be disabled to access the PLSYSMON registers and control the PL SYSMON unit. The APB/AXI and DRP parallel ports provide greater bandwidth access to the SYSMON units than the serial ports.

AMS requirements.

AMS.MON_STATUS [jtag_locked] bit (good clock).

APB slave interface (default mode).

°Check the AMS.PL_SYSMON_CONTROL_STATUS [accessible] bit.)

°No SYSMONE4 instantiation.

JTAG, I2C/PMBus arbitration.

VCCINT (check the [PL_INIT] bit.)
