    I2C slave without subaddressing

       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?
