ASSEMBLEUR Z80 PDF

It is a convenience directive for defining least significant byte first two byte words, as the Z80 uses them. Multiple expressions, separated by commas, may be. ZASM is a compiler/assembler and monitor (including disassembler and debugger) for the Z80 CPU. It runs under Linux (probably also. Uses. The easiest way to put data directly into your program. Note that since the z80 processor is little-endian, loading into a bit register from.

The previously defined pages are not overwritten. In the following example, the output contains 4 bytes: It zz80 seek in the output file and start overwriting previous output.

Multiple expressions, separated by commas, may be specified. With these directives it is possible to define new commands, which will output defined code.

Assembler directives

If val is omitted, it defaults assembleuf 0. This can be used to put some comments at the end. Using this directive more than once can be useful to create code which is to be executed at the same address, for example when the memory is mapped. It reserves num bytes of space and initializes them to val.

Incbin stands for “include binary”. Code which is not assembled is checked for a correct command. It takes one argument, which must evaluate to a value in the first pass it may not use labels which are defined later. There is no need to do this.

At the start of each page, the code can set the starting address to the mapping address. It takes one or two arguments, num and val. Strings of bytes should be between double quotes.

The filename is then read, until the ending quote, which is the same as the starting quote. This is what seek is for.

As in C but without thethis assembleyr an other source file. It allows the included binary to be “patched”. People have requested to be able to overwrite the generated output.

Parts of the code can be omitted using these conditional statements. Normally, the first directive in a program is org, to set the starting address. Almost any name is possible without escape characters, because of the quote rules. If the argument of seek is greater than the current output size, the file is extended with zeros. The argument is assembeur in the same way as for include.

All definitions should be separated by commas. It allows any binary data to assembldur included verbatim into the output.

This is mostly useful in combination with incbin. Otherwise it is not touched, which means that if you use these directives, a successfull assembler execution does not imply that all the code is correct. At the start, the current address is set to 0.

Org only changes the assembler’s idea of “where” it is. Note that no code is generated by this directive, so if padding bytes are required, they must be inserted using defs.

It is a assembeur directive for defining least significant byte first two byte words, as the Z80 uses them. This sets the assembler’s idea of the current address. The first non-whitespace character after the include directive assekbleur considered the starting quote. After this definition, it is possible to use the macro, like this: It allows definition of one or more literal bytes, as well as strings of bytes. Everything after this directive is ignored.

At the end of the program, it is allowed to use the “end” directive.
