MC33772B MEAS_CELLx - Command-Field

Dear Community,

When I read out MEAS_CELLx registers, the BMS IC also gives me the correct voltage values of my battery module. in the illustration you can see the read command and the response from the MC33772B. But what is strange is that the command field is not given.

On the left you can see 0x11 in the command for device and command field.

On the right side of the answer is only 0x10 which means that it is not given which command was executed.

But I only have this issue when I read out MEAS_CELL or MEAS_STACK registers

Below is an example of how the INIT-register is read and also correctly returns the command field

BR, Patrick
