IIC/SMBus on ML410 Platforms

Table 2-35 lists the function, part number, and addresses of the IIC devices on ML410
platforms. These devices include EEPROM, temperature sensors, power monitors, and a
Real Time Clock.

Notes:
1. This signal connects to U20 therm_l on the LM87. See data sheet for additional details.
Figure 2-19 shows a block diagram of the FPGA in relation to the SMBus accelerator and
the IIC bus.
Note:
Either the FPGA or the ALi M1535D+ can master the IIC bus, but not simultaneously.
