      RESET pin.

      The RESET pin of ST7789V is active low.
      If connected directly the MCU pin should be configured
      as active low.

      D/CX pin. If configured, 4-lines serial interface is used, otherwise
      3-lines serial interface is used and a D/CX bit (9-bit) is added to
      the protocol.

      The D/CX pin of ST7789V is active low (transmission command byte).
      If connected directly the MCU pin should be configured
      as active low.
