I'm working on a project with the MCU KL27Z.
I have a problem with the 9th bit on the I2C bus. The SDA line doesn't go all the way down (as ASK), it only goes half way down. I found that the solution should be making the SDA pin open drain, but i there´s no option to do that.
I´d like to know if there's a solution to this problem and how to do it.
