Motorola MVME162 manual General Purpose Readable Jumpers Header J22

Hardware Preparation and Installation

2General Purpose Readable Jumpers Header (J22)

Header J22 provides eight readable jumpers. These jumpers are 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).

Note

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).
