HPS I2C Pins
In addition to the three I2C_EMAC controllers, there are two additional I2C controllers (I2C0 and I2C1) for dedicated I2C usage in the Intel® Stratix® 10 HPS.
The I2C protocol requires pull-up resistors to VCCIO_HPS on both the serial data and serial clock signals for them to function correctly. The value of the pull-up resistor varies depending on your board loading, but it is typically 4.7-kΩ or lower.
