TC375: I2C SDA not pulled high after first byte successful read Attachments are accessible only for community members. Log in Markus4711 Level 3 12 Apr 2023 Dear all, I using the TC375 Lite Kit. On the Microbus interface I connected a click board that contains the ...
Let's say with a 100MHz input clock and the I2C Master is operating in normal mode of 100KHz. For SCL_HIGH and SCL_LOW, the register value is (10us/10ns) divide by 2 assuming high and low is same (duty cycle 50:50). For SDA_HOLD, it is (your ...

We are using an I2C slave controller and like to know how to properly constrain bidirectional SDA and SCL lines to meet setup and hold time requirements. I searched on the internet and cannot find anywhere advising what constraints to use for I2C SDA, SCL bidir...
