MPQ2024 I2C read operations

Hello,
I have a question about the I2C read sequence for the MPQ2024 device without repeated start. The datasheet states in the read sequence that there is a repeated start between the write and read part. Due to some limitations of the I2C host, the repeated start is not supported. Is there a way to work around this?
In the current solution there is a stop condition before reading the register content and PEC byte. Unfortunatelly the PEC byte isoutput with the value 0. Is there any connection?

Hello dennis.drews,

I will check in with our team, but I do not believe that there is a way to work around it. The device was set up to function with the repeated start.

I would say that getting a value of 0 for the PEC could be an indication of an issue.

Hello dennis.drews,

A workaround is not possible as it is built into our hardware.
