2.3.2.4. Programmable Current Strength

You can use the programmable current strength to mitigate the effects of high signal attenuation that is caused by a long transmission line or a legacy backplane.
Table 7.  Programmable Current Strength Settings for Intel® MAX® 10 DevicesThe output buffer for each Intel® MAX® 10 device I/O pin has a programmable current strength control for the I/O standards listed in this table.
