I am using UPSD 3334A in I2C slave mode.

For this I just put the address in S2ADR and AA and ENII in S2CON.

When masters send STA+ADDR it recognize it and generates an interrupt and sets ADDR to 1.

At this stage, It ties the SCL line to 0, and stopping the exchange waiting what ?

Does anyone know what to do about it ?

Does anybody have a programming manual showing step by step what to do ?

Thanks in advance

I believe your issue was resolved by an ST AE. If not, please state where you are with your issue.

An I2C driver for the uPSD3300 will be released later this month along with some demo code. This code will be available on the DK3300 CD as well as on the www.st.com/micropsd website under software downloads.
