Hi Peter,

Can you share full long part number you are using, so we know what is pre-programmed in the device?

Katie

Hi Peter,

as we are discussing your custom design I would like to move this thread to the internal forums. Do you have a direct point of contact at TI who you can work with?

In general you have to clear all the interrupts for the nINT to go high but if it is configured as ENDRV then the MCU has to write it high.

regards,

Niko
