A.11. I2C

I2C supports communication between integrated circuits on a board. It is a simple two-wire bus that consists of a serial data line (SDA) and a serial clock (SCL). The MAX® 10 and the Agilex™ 7 devices use the I2C for reading and writing to the various components on the board such as programmable clock generators, VID regulators, analog-to-digital converters (ADC), and temperature sensors.

You can use the Agilex™ 7 or MAX® 10 as the I2C host to access these devices, change clock frequencies or get status information of the board such as voltage and temperature readings.
