Hello Dears,

I am working on interfacing MSP430 with NT3H1101 with I2C. I could not read from the NTAG as the SDA is pulled low on 9th clock pulse. I found that it is related to clock stretching bit on register I2C_CLOCK_STR. my question is how can  disable the I2C clock stretching and i cannot access the NTAG because the 9th clock is pulled low?

what shpuld i do that i can communicate with the NTAG?

best regards,

tarik
