- Clocks
- The XRAM has one main clock that is driven by an output from the clock and reset unit in the PMC (CRP) or by the PL. This is dependent on the setting of the xxxxxx register. This clock is used by the crossbar switch, the XMPUs, and the memory banks.
- Resets
- Reset can always be from the CRL module with an option to reset from the PL.
- System Interrupts
- The system interrupt signals go to the GICs, PSM interrupt controller, and the PL. The XRAM interrupts are included in a table in the System Interrupts chapter.
- System Errors
- The system error signals go to the PMC EAM and the PL. The XRAM errors are included in a table in the System Errors chapter.
PL access to XRAM clocks, resets, interrupts, and errors is only supported in devices that support the PL interface to the XRAM. See Devices with Accelerator RAM and Access Ports.
