Zynq I2C Bus Glitch Question (Regarding AR# 61861)

Jump to solution

Hi,

If we run the I2C bus master on the Zynq PS pins at 100KHz or slower i.e. standard mode, not fast mode are these glitches still a potential issue please or is it more related to the speed capabilities of the attached I2C bus peripherals ?

Thanks,

Ian

The glitch filter is missing, and needs to be done by the user.

the chip, no matter what speed the I2C is, still sees very short glitches as valid data so they need to be filtered.
