PSoC™ 5, 3 & 1

 I need to make a I2C slave without subadressing using the CY8C21534. The data to read and write is always 2 byte so with every read and write, these both bytes are transferred.

   

In fact the slave should act as a PCA8575 I2C port expander.

   

What I2C module can I best use for this? EZI2C always seems to expect a subadress.

   

Is there already an example for this?

   

Thanks.
