PSoC 5, 3 & 1 MCU

I have used sucessfully miniprog3 for I2C data exchange with PC as Master.

   

BUt when it came to PSOC1 The miniprog3 reads or writes wrong data!

   

for example :

   

write 04 01 (addres 4 first byte of 1) is sucessfully acknowledged up to 0B (data) (w 04+ 01+ p) and (w 04+ 0C- p)

   

write 04 0C up to FF doesn't get acknowledged

   

speed 100k on both sides, no external pullups resitors(as it was not required with psoc 3)

   

What is wrong?

   

I played with P10 and P11 pin configuration from res-pullup to open-drain-low but no success
