Detailed Description

Low-level MCU 8080 8-/16-bit parallel interface driver.

If the MCU-driven low-level parallel interface is enabled by module lcd_ll_parallel_mcu, the implementation of the MCU low-level parallel interface has to define a variable lcd_ll_par_driver of this type. All or a set of members have to point to the low-level parallel interface functions implemented by the MCU. For functions that are not implemented by the MCU, the members have to be set to the corresponding GPIO-driven low-level parallel interface functions provided by the LCD driver.
