The timing specs for both are the same but when using the I2C1 (the one using standard I/O) the SDA line change status exactly at the SCL line edge and that may produce and stop or restart condition. On the other hand, I2C0 change the status at while the SCL is low.</SPAN><BR /><BR /><SPAN>Is there a way to solve this? I couldn't find any register to configure this, just to configure the clock duty cycle which does not help on this issue.</SPAN><BR /><BR /><SPAN>I attach a pic showing the waveform.</SPAN><BR /><BR /><SPAN>Regards,</SPAN><BR /><BR /><SPAN>Mikel</SPAN><BR /></BODY></HTML> Wed, 15 Jun 2016 16:40:52 GMT https://community.nxp.com/t5/LPC-Microcontrollers/I2C-timing/m-p/522709#M5345 lpcware 2016-06-15T16:40:52Z Re: I2C timing https://community.nxp.com/t5/LPC-Microcontrollers/I2C-timing/m-p/522710#M5346 <HTML><HEAD></HEAD><BODY><SPAN>bump</SPAN></BODY></HTML> Sun, 19 Jun 2016 01:11:14 GMT https://community.nxp.com/t5/LPC-Microcontrollers/I2C-timing/m-p/522710#M5346 lpcware 2016-06-19T01:11:14Z
