I am attempting to read some of my script registers through the user UART interface (UART1). I am using the address given to me by the MCEWizard compiled .ldf file for my script register (see screenshot below). All other read register commands for different registers (example: MOTOR_CURRENT register, app id = 1, address = 154) work properly and I can receive a non-zero result from them. When I try to read the value of my script registers (example TrqBoost_L register, app id = 4, address = 130), they always read as zero, no matter what. I know that the register contents are not ACTUALLY zero because I can read them through MCEDesigner, and they read as what I expect (non-zero value). Can someone help me with this?

I am having a problem with viewing scaled current on the IMC101TT038XUMA1. I have the parameters set to use Leg Shunt, and have current sensing gain and offset circuits going to the IMC101 inputs IU, IV, and IW. See below for schematic.

I've noticed that the REFV and REVW pins of the IMC101 (DAC generation of voltages for gatekill overcurrent comparator) are at ZERO volts, even when leg shunt mode is enabled. These should be at the value that corresponds to overcurrent (for me about 4.1V). The REFU pin shows the correct DAC value of 4.1V.

Additionally, when reading the value of IV and IW in MCEDesigner, the reading shows the current as the minimum value (-20.1A) with some noise. All of this is true before even starting the motor. Because of this error, the gatekill fault is always active, and therefore prevents the motor from running. 

Can someone help me with this problem? Do the REFU, REFV, and REFW inputs need to be tied together?

Hello, I am using your TLE92104131QXXUMA1 motor driver. Since CPUV is 1, I get SUPE = 1 error and I cannot exit Fail Safe Mode.
Writing in the datasheet;
1. Clear GENSTAT register.
2. Write WDTRIG bit to 1 (GENCTRL1) within the watchdog period.
3. Write WDTRIG bit to 0 within the watchdog period3).
I apply these situations, but I cannot clear the GENSTAT registry. Can you help with this?
