Wiggle I2C SCK when SDA is held low on FX2?
Stop me if you're heard this one before. I need to fix a hardware issue in software. <G>
I need to wiggle the SCK signal on a FX2 while the SDA line is being held low. I am assuming that SDA being held low results in BERR error status bit being set and no I2C data transfer occurs, thus no clocking to clear the stuck I2C peripheral. Since SDA and SCK are not also GPIO pins there seems no way to do this. Is there some double secret handshake way of getting SCK to give me some edges?
