PSoC 5, 3 & 1 MCU

Not applicable

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
