General-Purpose Readable Jumpers Header (J22)
Header J22 provides eight readable jumpers. These jumpers can be read as a
register (at $FFF4202D) in the MCchip LCSR (local control/status register).
The bit values are read as a zero when the jumper is installed, and as a one
when the jumper is removed.
If the MVME162BUG firmware is installed, four jumpers are user-definable
(pins 1-2, 3-4, 5-6, 7-8). If the MVME162BUG firmware is not installed, seven
jumpers are user-definable (pins 1-2, 3-4, 5-6, 7-8, 11-12, 13-14, 15-16).

Pins 9-10 (GPIO3) are reserved to select either the Flash
memory map (jumper installed) or the EPROM memory
map (jumper removed). They are not user-definable.
The MVME162 is shipped from the factory with J22 set to all zeros (jumpers on
all pins).
