The MVME2700 base board has provision for 1MB of 16-bit Flash
memory. The RAM200 memory mezzanine accommodates 4MB or 8MB
of additional 64-bit Flash memory.
The Flash memory is organized in either one or two banks, each bank
either 16 or 64 bits wide.
To enable Flash bank A (4MB or 8MB of firmware resident on soldered-
in devices on the RAM200 mezzanine), place a jumper across header J9
pins 1 and 2. To enable Flash bank B (1MB of firmware located in sockets
on the base board), place a jumper across header J9 pins 2 and 3.

In synchronous serial communications, you can configure serial port 4 on
the MVME2700 to use the clock signals provided by the RxC signal line.
The configurations for the MVME712M-compatible and MVME761-
compatible versions of the base board require different settings for port 4
to either drive or receive RxC (default).
