Configuration Scheme MSEL[2:0]
AS (Fast mode - for CvP)6 , 7 001
6 To support AS fast mode, the VCCIO_SDM of Agilex™ 7 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 120 ms of power stable to PCIe* link active time.
7 The 10 ms delay before beginning configuration is still present in the Agilex™ 7 AGF 019/023/035/040, AGI 019/023/035/040, and AGM 032/039 devices. For information on bypassing the delay, contact Intel Premier Support and quote ID #15015203262.
