You must also specify the configuration scheme on the Configuration page of the Device and Pin Options dialog box in the
Intel Quartus Prime Software.
(5)
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 Intel Agilex device begins to access it.
(6)
If you use AS Normal mode, you must fully ramp the V
CCIO_SDM
supply to the recommended operating condition within 10 ms.

JTAG configuration works with any valid MSEL settings, unless disabled for security.
