I2C Slave transmitter problem

Hi!

Could any one tell my how clear ADDR flags in SR1 register.

In documentation to library 3.0.1 we can read that:

''This bit is cleared by software reading SR1 register followed reading SR2''

I do something like this:

I2C_GetFlagStatus(I2C1,I2C_FLAG_ADDR);

(void)(I2C1->SR2);

but after that flag is still on, and i can't get ''slave transmitter address matched'' again :[

Any sugestions?

Regards,

Maciek
