I2C communication 

Hello,

I'm trying to write 0x52 adress to 0x02 value but i cant figure out data type
 
Actually i tried : 

```
i2c = CyI2C(dev)
i2c.debug=1

cfg = i2c.prepare(slaveAddress=0x1b, isStopBit=1, isNakBit=1)
data=????
i2c.write(cfg, data)

```
what data type must be ?
