Op Codes Listed Numerically

This chapter provides an easy reference for locating instructions by their

operational codes.

Sample Program Listing

A sample program shows how the instructions, using many of the avail-

able memory modes, will translate into object code after assembly.

Manual Conventions

The following assumptions and conventions are adopted to provide clarity

and ease of use:

Courier Typeface

Commands, code lines and fragments, bits, equations, hexadecimal

addresses, and various executable items are distinguished from general

text by the use of the

Courier typeface. Where the use of the font is not

indicated, as in the Index, the name of the entity is presented in upper

case.

•

Example: FLAGS[1] is smrf.

Hexadecimal Values

Hexadecimal values are designated by lowercase h and appear in the

Courier typeface.

•

Example: R1 is set to F8h.

Brackets

The square brackets, [ ], indicate a register or bus.

•

Example: for the register R1[7:0], R1 is an 8-bit register, R1[7] is the

most significant bit, and R1[0] is the least significant bit.
