    CY8C4014FNI-421AT I2C Internal pull ups




      I have a question with internal pull-ups for PSoC 4 device (CY8C4014FNI-421AT). As per datasheets it can be seen that I can enable internal I2C 5.6 KOhms weak pulls ups through the below commands in firmware.





      Can you please advise whether using internal resistors on I2C data & clock lines provides similar performance as that of the external pull-ups and we can eliminate the use of external pull-ups to save space in the design?


      Best Regards,
