CHAPTER 5: ASSEMBLER

5.7.6 Location Defining Pseudo-Instructions (.org, .bank, .page, .align)

The absolute addressing pseudo-instructions (.bank, .page, .align and .org) work to specify absolute

location of a section in different precision such as bank number level, page number level, 2n words

alignment level and complete absolute address level.

The .bank and .page pseudo-instructions are applicable to CODE section only, others are applicable to

any kinds of sections (CODE and BSS sections).

.org pseudo-instruction

Instruction format

.org <Address>

<Address>:

Absolute address specification

• Only decimal, binary and hexadecimal numbers can be described.

• The addresses that can be specified are from 0 to 8,192 (0x1fff).

• One or more spaces or tabs are necessary between the instruction and the address.

Sample description:

.code

.org 0x0100

Function

Specifies an absolute address location of a CODE or BSS section in an assembly source file. The section

with the .org pseudo-instruction is taken as an absolute section.

Precautions

• If an overlap occurs as the result of specifying absolute locations with the .org pseudo-instruction, an

error will result.

Examples:

.bss

.org 0x00

.comm RAM0 4 ... RAM secured area (0x00–0x03)

.org 0x01

.comm RAM1 4 ... Error (because the area of 0x01–0x03 is overlapped)

•When the .org pseudo-instruction appears in a section, a new absolute section starts at that point. The

section type does not change. The .org pseudo-instruction keeps its effect only in that section until the

next section definer (.code or .bss) or the next location definer (.org, .align, .page, or .bank) appears.

Example: :

.code ... The latest relocatable section definition.

:

.org 0x100 ... Starts new absolute CODE section from address 0x100.

:

.bss ... This section is relocatable not affected by the ".org" pseudo-instruction.

:

.code ... This section is also relocatable not affected by the ".org" pseudo-instruction.
