MC33PT2000 output inconsistency

Hello, 
I am currently using NXP's official evaluation board to debug solenoid valves. The Loaddata file in the software is generated by Mc33PT2000 Developer Studio, ensuring that the current block corresponds to the bank. The microCode codes of the two banks are also the same and the solenoid valves are the same. They have also been exchanged. However, the inj3 signal output by bank2 and the inj5 signal output by bank3 are different. In the data-RAM array, the current and voltage configurations of both are the same. Bank2 and 3 are not broken and can work normally. The only difference is that the two have the same configuration (voltage, current, time, microCode code, load solenoid valve, etc.) but different outputs. This makes it difficult for me to understand
Looking forward to your support.

Hello Jozef
Thank you for your help. I used many routines, including the one you provided, but the results did not meet my expectations. Afterwards, I did not connect the load and found an abnormality. The initial voltage value of bank 1 was inconsistent with other banks, and I recorded it as a picture,
Looking forward to your help. Thank you!
