What is the VCL and VD pins used for?

Other Parts Discussed in Thread: UCD9222

Hi,

I want to know how to deal with the VCL and VD pins of C6678 and what ther are used for. In the TMDXEVM6678L EVM board, these signals are all connected to a FPGA with no futher informations. Can I connect them directly to the PMBUS_CLK and PMBUS_DATA pins of UCD9222?

I know the VCL and VD pins are the I2C interface of C6678's SmartReflex module, but I can't find any document to show more details about them. Are there any registers to control the SmartReflex module that not yet listed in the 6678 datasheet, for example, registers for sending power control commands to UCD9222 through the VCL and VD interface?

regards,

Cheng
