Hi guys,

I use CYPD3020 controller for my project. I want to use Timer/Counter block with input counter. When I connected digital input pin and Counter I got an error: Pin guidance unavailable: 'Pin_1(0)' cannot be placed at P3[3]. P3 cannot be used for routed connections.

Could you help me?

Hi Nazar,

Could you please try assigning Pin_1 to another pin from any other port and check if the error still occurs? Please attach your complete project if possible for us to take a look.

Hi Sananya,

Yes, I tried to assign another pin from another port, the error is still there.

Hi Nazar,

Thanks for the project, I was able to reproduce the issue. The reason for the error is that the GPIOs dedicated for TCPWM block in CCG3 dont support input function and hence cant be allocated to the Timer/Counter as count input. In the DWR file, only the pins in the list which have TCPWM tr_in mentioned, can be routed to the trigger inputs in the TCPWM block and CCG3 doesnt have any such pin since all of them are available only for output function.

 

Best Regards,

Sananya
