AM1707, Using both EMIFA and LCD Controller

Other Parts Discussed in Thread: AM1707

How does one go about connecting both an LCD and an NAND Flash (TSOP48 parallel type) to the AM1707... Both of these use the pins connected to LCD/EMIFA; perhaps I'm missing something, but it does not follow that something receiving constant data (LCD) can be interrupted by an access to the FLASH, without dire consequences to the visual aspect of the LCD, or broken access to the Flash.

Thanks,

    You will only be able to use an 8-bit NAND Flash, since the upper 8 bits of the EMIFA interface would be used for the LCD controller instead. For a raster type display with no frame buffer, the panel requires constant data and switching to read/write from the Flash would corrupt the image.
