This enables the LCD controller (LCDC) in the AT32AP7000. Since the

LCDC is multiplexed with MACB1 (LAN) Ethernet port, only one can be

enabled at a time.

optional peripherals to the Atmel NGW100.

This choice disables the detect pin and the write-protect pin for the

The MCI pins can be reenabled by editing the "add device function" but

this may break the setup for other displays that use these pins.
