7.3.6.1. I/O Standards and Drive Strength for Configuration Pins
The standard I/O voltage for Intel® Cyclone® 10 GX devices is 1.8 V. The drive strength setting for dedicated configuration I/O are hardwired. The default drive strength for dual function configuration I/O pins during configuration is 1.8V at 50 Ω. When you enable the configuration pins, the Quartus® Prime Pro Edition software sets the CVP_CONF_DONE pin to a drive strength of 1.8 V CMOS 4 mA, and the INIT_DONE and CRC_ERROR pins to a drive strength of 1.8 V CMOS 8 mA.
