Hi there Supporter,
TM4C123GH6ZRB's datasheet describes I2CSCL's corresponding port pin should not be configured as open drain. However, its buffer type is exactly open drain.
So, I am a little confused. Can you let me know what does the description certainly mean?
And also, the description says the pin has active pullup. Does it mean only I2CSCL has internal pullup but I2CSDA doesn't?
Regards,
S.P. Lin
