Hello Team,
I got question from my customer if 941AS support interrupt in case error case.
I understand this is for passing INTB_IN at DES to INTB at SER. but I also found bit6 that indicate LOCK for INTB.
I think this is one of error detection for INTB in case lost LOCK. If some event like ESD cause LOCK lost, INTB will be dropped to low. Is my understanding correct?? and Is there any interrupt option to detect error??
Thank you.
Hey Harry,
So if you want to monitor the interrupts you can monitor those on 0xC7 ISR. Basically bit6 will reflect the status of the downstream Des. So at power-up when you plug in the Des this bit6 will be set high to indicate there is a downstream Des connected. In case of an ESD event, or power glitch, this 0xC7 register will reflect that on bit6. However, if you want it to also reflect the video Lock status then you need to enable RX_DET_SEL in register 0xC2.
Besides monitoring the status on 0xC7 via registers, enabling these bits on 0xC6 will output that status of the interrupts onto the INTB pin.
