Is there a diagram anywhere that shows what the SDA Hold Value and the SCL Hold Start/Stop Values are?</P><P></P><P>Also, it says those values are in 'Clocks', so does that mean that if I am running at 8Mhz, then the SCL Hold Value for the first entry in that table would be 7/8000000, or 875 nanoseconds? It is just unclear to me, so any info will be much appreciated. Thank you</P></BODY></HTML> Wed, 19 Mar 2014 12:51:59 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/I2C-SCL-Start-Hold-Times/m-p/299566#M12452 LSmith-NK 2014-03-19T12:51:59Z Re: I2C SCL Start & Hold Times https://community.nxp.com/t5/Kinetis-Microcontrollers/I2C-SCL-Start-Hold-Times/m-p/299567#M12453 <HTML><HEAD></HEAD><BODY><P>Please related the SDA hold time, the SCL start hold time, and the SCL stop hold time interpretation at I2C Frequency Divider register (I2Cx_F) [ICF] bit description.</P><P>It located at page983 of K12P80M50SF4RM.</P><P>It also provides an example.</P><P><BR />Wish it helps.</P><P></P><P>Best regards,<BR />Ma Hui</P><P></P><P>-----------------------------------------------------------------------------------------------------------------------<BR />Note: If this post answers your question, please click the Correct Answer button.
