Just set up a PSOC 4000 project which comprises of 1 Timer, 1 I2C, 1 digital input pin (external terminal). Add in interrupt to the digital pin, click generate application and got the error:
E2809: Unable to find a valid placement for pins and fixed-function blocks. See the Digital Placement's Detailed placement messages section in the report file for details.
Doesn't PSOC 4000 support external signal as interrupt?
Please see atteched project file.
Solved! Go to Solution.

Would you mind to setup the interrupt for the pin component like below:
Then connect the ZC_INTR to the irq of ZC pin:
The reason that the connecting the ZC_INTR to the ZC pin(as below) does not work is the PSoC4000 family devices do not have port interface digital routing inside.

I made the change. It works for the C8YC4013SXI-411 only. Not for the C8YC4013SXI-400 & C8YC4013SXI-410. Not enough resources?
