Summary of Changes

This is the fifth edition of the Programmer’s Reference Guide. It

supersedes the March 2001 edition and incorporates the following updates.

Date Description of Change

January 2001 A caution about DRAM component requirements was added to the DRAM

Attributes Register and Sizing DRAM sections of Chapter 3.

January 2001 In descriptions of the general-purpose software-readable header (J10/J17), such

as Figure 1-4 in Chapter 1, information on bit 1 (SRH1) was updated to

correctly reflect the functionality of that bit.

March 2001 At various locations in the manual, such as P2 I/O on page 1-7, information has

been added to accommodate the

MVME2300SC variants of the board.

The contents of the manual have also been reorganized somewhat to conform

with present Computer Group practice for board manuals.

June 2001 All data referring to the VME CSR Bit Set Register (VCSR_SET) and VME

CSR Bit Clear Register (VCSR_CLR) has been deleted. These registers of the

Universe II are unavailable for implementation as intended by the MVME

materials and the Universe II User Manual.
