Hi,

 

In first, I apologize for my english, i'm not very good

 

I work on a K10 and i would like use I2C to communicate with an RTC (rv-3029)

 

When i write on the bus, it's works perfectly. But, when the RTC send à ACK or a Data, it result an middle state (like the pictures)

 

it's seems good, except this half state

I try to configure the Open drain on the port, but the flag busy is always set after that.

 

PORTB_PCR0 = 0|(PORT_PCR_MUX(0x2));

PORTB_PCR1 = 0|PORT_PCR_DSE_MASK|(PORT_PCR_MUX(0x2));


Thx for reply
