The ST7701(S) is capable of DSI burst mode, which is more energy efficient than the non-burst modes. Make use of it. The ST7701(S) is capable of DSI non-continuous clock, since it sources the TFT matrix driver clock from internal clock source. The DSI non-continuous clock further reduce power utilization. The ST7701(S) uses DSI LPM for command transmissions, make sure this is configured correctly in the DSI mode flags.
