Hi,

I need to detect changes in 16 inputs using S12XDP512. This inputs are critical, therefore, I cannot read them using a timer interruption (I could miss data). I was thinking about using Enhanced Capture Timer but it only has 8 channels. Any suggestions?

Thanks in advanced,

Jaime

Port H, port J and port P are interrupt capable. You can detect rising or falling edge on every port H/J/P pin.

Thank you for your reply,
I only have 4 pins for port J since I am using the 112 package, and I am also using the 2 SPI from port H, thus I am missing 4 extra pins... What do you suggest? Could I use enhanced timer capture?
Thanks

Of course you can use ECT. Please look in manual for input capture.
