About this Manual
This manual serves as a register reference guide to the M56 graphics controller.
•
Chapter 1
outlines the notations and conventions used throughout this manual.
•
Chapter 2
provides a detailed description of the registers.
•
Appendix A
provides several cross-referenced lists (sorted by Register Name and Address).

Nomenclature and Conventions
1.2.1
Numeric Representations
•
Hexadecimal numbers are appended with "h" whenever there is a risk of ambiguity. Other numbers are assumed to be
in decimal.
•
Registers (or fields) of identical function are sometimes indicated by a single expression in which the part of the
signal name that differs is enclosed in [ ] brackets. For example, the eight Host Data registers — HOST_DATA0
through to HOST_DATA7 — are represented by the single expression HOST_DATA[7:0].

Register Description
All registers in this document are described with the format of the sample table below. All offsets are in hexadecimal
notation, while programmed bits are in either binomial or hexadecimal notation.
Field Name
DST_WIDTH
(mirror bits 0:7 of DST_WIDTH:DST_WIDTH)
DST_HEIGHT
(mirror bits 0:7 of DST_HEIGHT:DST_HEIGHT)
[ W] (Reserved) 15: 0 DST_WIDTH 23: 16 Destination width: range 0 to 256 (ZERO extent)

Description
Destination Width Note: This is an initiator register. Y is incremented
at end of blit. Write 15: 0 to E2_DST_X, Write 31: 16 to
E2_DST_WIDTH, then signal blit_start. E2_DST_Y = E2_DEST_Y
(+/-) E2_DST_HEIGHT as function of direction after blit is complete
Destination Height Write 15: 0 to E2_DST_Y, Write 31: 16 to
E2_DST_HEIGHT
