A.6. I2C
The MAX® 10 and Agilex™ 7 devices use the I2C for reading and writing to the various components on the board such as programmable clock generators, voltage regulators, temperature sensors, and EEPROMs. You can use the Agilex™ 7 or MAX® 10 as the I2C host to access these devices, change clock frequencies, or get board status information such as the voltage and temperature readings.
