If you are using SPI you do not need a tristate,
only I2C requires a tri-state for the SDA bi-direction
(usually don't need one for SCL).

If you are using SPI I would remove the tristate.
Make sure the CSn signal goes low, didn't review
the data sheet fully, don't know if it can be tied
low or if it needs the transition.
