2.5.2. MSEL Settings

After power-on MSEL[2:0] pins specify the configuration scheme for Agilex™ 7 devices. Use 4.7-kΩ resistors to pull the MSEL[2:0] pins up to VCCIO_SDM or down to ground as required by the MSEL[2:0] setting for your configuration scheme.

Configuration Scheme MSEL[2:0]
Avalon-ST (x32) 000
Avalon-ST (x16) 101
Avalon-ST (x8) 110
AS (Fast mode – for CvP)4 device begins to access it. 001
AS (Normal mode)5. 011
JTAG only6 111
You must also specify the configuration scheme on the Configuration page of the Device and Pin Options dialog box in the Quartus® Prime Software.

4 If you use AS Fast mode, you must ramp all power supplies to the recommended operating condition within 10 ms. This ramp up requirement ensures that the AS x4 device is within its operating voltage range when the Agilex™ 7
5 If you use AS Normal mode, you must fully ramp the VCCIO_SDM supply to the recommended operating condition within 10 ms
6 JTAG configuration works with any valid MSEL settings, unless disabled for security.
