NOTE: If an LCD panel is not used, this interface can be used to control any MCU-like peripheral.
See your device-specific data manual to check the LIDD features supported by the LCD controller.
Table 23-3 describes how the signals are used to interface external LCD modules, which are configured
by the LIDD_CTRL register.
