NHS3152 I2C connection problem

Hello,

 

I'm trying to connect a peripheral IC to NHS3152 demo board. I'm using the I2CIO library part and informations provided in release_mra2_11_2_nhs3152 SDK. I'm facing the following issue:
I am not able to select the device via I2C - the address 0xEA should be sent, but on the bus i am observing a different output:
I2C lines

The data is recognized as '212' but it should be '234'
The system runs at 4 MHz, and the I2C is set to 100kHz.

Thanks in advance for any help provided.
Damian
