0193H: ID CHIP AND I2C LINK (FPGA)
ID chip is a single wire interface. This chip can also be read by the onboard BMC microcontroller. It
is recommended that if you use the IPMI function on the T6010, use the standard IPMI interface to
retrieve board ID. I2C is a bit-banging interface. Use of register 1A8h to 1ABh is recommended as
the new interface to onboard I2C memory.
