STM32F769 LTCD spurious interrupt
I'm working with the STM32F769I-Disco board which uses DSI to drive its LCD display.
I'm seeing LCD-TFT global Error interrupts being raised but both the LTCD->ISR and LTCD->IER are both zero.
I've scanned through the app notes for DSI and I can't see any mention that the DSI can trigger a LCD-TFT interrupt even though the LCD own registers are not set to do so.
Within the ISR I see that DSI->ISR1:GPRDE is set which would indicate some form of transfer issue.
It only happens during the initial startup of the app, not once its established and running but I don't like to have unknowns lurking which may be problems for later on.
Do you think this may be a possible explanation and is having a null ISR sufficient to handle it since there is no LTCD->ISR value to clear in the LTCD->ICR register?
