Hello.

I have questions about SHORT-TO-BATTERY (STB) DIAGNOSTICS of ADV7281-M.

 

There is a following description about SHORT-TO-BATTERY on UG-637.pdf page.13
http://www.analog.com/static/imported-files/user_guides/ADV7280_7281_7282_UG-637.pdf

 

"When the DIAGx pin voltage exceeds the diagnostic slice level voltage, a hardware interrupt is triggered and indicated by the INTRQ pin.
A readback register is also provided, which allows the user to determine the DIAGx pin on which the STB event occurred."

 

I think there must be interrupt status, clear and mask registers related to DIAGx pin for interrupt.
But I can't find the interrupt registers for DIAGx.
Which interrupt registers can we use for SHORT-TO-BATTERY DIAGNOSTICS function?

 

Thank you.
Best regards.
