Tool/software:
Hello,
First, is it possible for the BQ25756 to stretch the clock, and if so, can you help with the following situation?
I have a BQ25756 which is exhibiting unexplainable behavior on the I2C clock, causing data to hang low for 1.6s.
The unique configuration of this setup is that I am using a switch (TS3A24157RSER), to toggle between two BQ25756 I2C clock/data.
I am seeing random clock cycles which have a very short duration, and no discernable pattern.
I am using an ATSAMS70Q20B as the controller.
I am attaching captures from a signal analyzer showing this behavior both on write and read.
If you look at this on a oscilloscope, there appears to be a partial clock cycle with anywhere from 1V-2V amplitude, which explains why the signal analyzer sometimes shows the pulse, and sometimes doesn't.
Thank you.
