5.17 SMBus Interface
The SMBus interface of the ICH10R is connected to on-board devices like Clock PLLs,
temperature sensors and the SPD PROMs of all twelve DDR3 DIMM memory modules. I
2
C Bus
Repeater of type PCA9515 is used to buffer the SMBus portion going to the SPD PROMs on the
DIMM. The BIOS reads memory configuration parameters from SPD PROM. To address more
than 8 memory I2C devices, the SMBus to the SPD PROMS is segmented.
