I2C Master Receiver

Hi,

I have a very serious problem in operating the uPSD3200 I2C hardware as master receiver mode with AT24C512 (Atmel) standard I2C eeprom chip .

The write direction from the microcontroller to the eeprom seems to be o.k .

However,when i want to read data from the eeprom it doesn't work .

From some reason the eeprom doesn't send me the data and the SCL line is not changing .

In the uPSD master receiver algorithm ,it says in step 4 to write 0xFF to S2DAT .Why?

Who is responsible for the SCL line when reading from the eeprom ?

Is there perhaps a similar driver for the uPSD 3200 implementing eeprom write/read ?

Thanks.
