Hello,

We are using a CY8C9520A-24 on one of our boards and we have some problem with I2C clock stretching when configuration and write gpio port.

on a block diagram I2C SCL input, but on page 1 “The I2C slave in this device requires that the I2C master supports clock stretching.” In this part tells about eeprom.

I don’t understand clock stretching when write gpio port is a normal?

Hi,

Kindly let us know the following details:

> As per our understanding of the problem, your question is 'Why is clock stretching happening' ?

> Which device are you using as I2C Master or the Host ? Is it a PSoC device?

> You have mentioned that you are able to observe this issue in one of the boards. Is this happening for other boards as well? If not can you perform an IC Swap test and let us know if the issue still exists ?

Best Regards

Ekta
