The contents of a PAL and the state of an 8-position jumper block
are translated to bit settings of the General Purpose Inputs Register,
Version Register and DRAM/SRAM Options Register when the
MC2 chip is reset. These registers are read only. Writes to these
registers are terminated without exception but do not change their
contents.

V10-V8 V10 - V8 are general purpose inputs which are
connected to three jumpers on the MVME162FX
board. Refer to the MVME162FX Embedded Controller
Installation and Use manual for jumper pin
definitions. If the bit is set to a one, the jumper is
absent; if it is a zero, the jumper is present. The
jumpers for V10 - V8 are located at J22-12/J22-11
through J22-16/J22-15 (for GPI2, GPI1, and GPI0),
respectively.
Refer to
V11
and 6. The jumper for V11 is located at J22-10/J22-9
(for GPI3). Refer to Chapter 1 for jumper pin
definitions.
Do not remove the jumper from J22, pins 9 and 10.
Doing so will cause the board to become inoperable.
V15 - V12 are general purpose inputs. Refer to the
V15-V12
description for V10 - V8. The jumpers for V15 - V12
are located at J22-2/J22-1 through J22-8/J22-7 (for
GPI7, GPI6, GPI5, and GPI4), respectively.
