There is a device that can set the Slew Rate setting value, but the setting value is not described in the Device Handbook. Please tell me about the setting value.

Quartus Prime

The values that can be set differ depending on the selected device family.
・Arria II GX, Stratix III, Stratix IV, Stratix V: 0 to 3
- HardCopy III, HardCopy IV: 0 to 3
・ Cyclone III, Cyclone IV: 0 to 2

The setting value "0" is the slowest, and the maximum value that can be set is the fastest.
If not set, the fastest value will be applied.

Please note that depending on the I/O Standard setting, there are devices that cannot set the Slew Rate.
