2.6. Board Monitoring through I2C SMBus

The standard I2C slave to Avalon-MM interface (read-only) shares the PCIe* SMBus between the host BMC and the Intel® MAX® 10 RoT. The Intel® FPGA PAC D5005 supports standard I2C slave interface and the slave address is 0xBC by default only for out-of-band access. Byte addressing mode is 2-byte offset address mode.

This section covers the telemetry data register memory map that you can use to access information through the I2C commands. The description column describes how the returned register values may be further processed to get the actual values. The units can be Celsius (°C), mA, mV, mW depending on what sensor you read.
