Part Number: TPS53676
Currently, I am using the TPS53676. The PMBus interface works normally at all times (e.g., reading IDs, setting voltages, etc.), but there is an issue with the AVSBus interface. Through an analyzer, I can see that the CLK and MDATA commands have been sent to the TPS53676, but SDATA does not return an ACK. I have verified the following information:
1. USER_DATA_08 (AVSBUS_CONFIG): value is 0x1 (for both rails), confirming 3-wire mode.
2. MISC_OPTIONS = 0x10 00 00 60 00
