The TC358767/TC358867/TC9595 are capable of DSI burst mode, which is more energy efficient than the non-burst modes. Make use of it.
The TC358767/TC358867/TC9595 are capable of DSI non-continuous clock, since it sources the internal PLL clock from external clock source. The DSI non-continuous clock further reduces power utilization. The TC358767/TC358867/TC9595 may use DSI LPM for command transmissions, make sure this is configured correctly in the DSI mode flags.
