Hello,

I am using CY8C4248AZI-L485 and I want to use CAN communication with the device, so i am required to have a 0.5% clock accuracy.

I saw the option to use an ECO, from what i understand this option requires that i connect an external crystal to the PSOC, the problem is that i can't find the pins that the ECO uses, neither in the pin configuration in PSOC creator nor in the datasheet, so maybe i misunderstood the use of the ECO,  so can anyone help in this matter?

Thanks,

Hi,

Use the pin P0.6 to connect a ECO to the device.

You can also find this information in the device datasheet  http://www.cypress.com/file/222206/download  Pg no 13 Pin outs section

Hi,

This is for using the ExtCLK, not the ECO. I want to use a crystal with the ECO
