AS (Fast mode - for CvP)6 001
6 To support AS fast mode, the VCCIO_SDM of Intel® Agilex™ device must be fully ramped-up within 10ms to the recommended operating conditions. The delay between the device exiting POR and the SDM Boot-up is shorter for the fast mode compared to the normal mode. Therefore, AS fast mode is the recommended configuration scheme for CvP because the device can conform to the PCIe 100ms power-up-to-active time requirement.
