Original question:
TMS320F280039C: PMBUS
当我使用pmbus进行写字操作，会在PEC字节进行时钟延展，从机也不能正确接收数据，这要怎么解决？
感谢您对TI产品的关注。我们正在核实您的问题，请等待我们的答复。
您好
To clarify, are you using the PMBUS module in master mode? If you are seeing clock stretching happening, this is due to the slave device pulling the line low and would be an issue/question relating to the slave device.
