2.10 I2C

The T1024 devices supports up to four I2C buses, to make the I2C resources equally

available to both local and remote systems. The T1024RDB uses I2C1 port to access on-

board devices, such as DDR3 DIMM, thermal sensor (ADT7461), EEPROM, RTC, and

clock PLL. The I2C2 bus uses multiplexers to partition the I2C bus into several channels.

Two mini PCIe slots use channels 0 and 1, and the PCIe slot uses channel 3.

The following figure shows the I2C subsystem.
