.bank pseudo-instruction
Instruction format
.bank
Absolute bank number specification
• Only decimal, binary and hexadecimal numbers can be described.
• The bank number that can be specified is 0 or 1.
• One or more spaces or tabs are necessary between the instruction and the bank number.
Sample description:
.code
.bank
1
Function
Specifies an absolute bank address of a CODE section in an assembly source file. The section with the
.bank
pseudo-instruction will be located at the top of the specified bank.
Precautions
• .bank is applicable to a CODE section only.
• When the .bank pseudo-instruction appears in a section, a new absolute section starts at that point.
The section type is fixed at CODE section. The .bank 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.
:
.bank 1
... Starts new absolute CODE section from bank 1.
:
.bss
... This section is relocatable not affected by the ".bank" pseudo-instruction.
:
.code
... This section is also relocatable not affected by the ".bank" pseudo-instruction.
:
• If the .bank pseudo-instruction is defined immediately after a section definer (.code or .bss), the
section definer does not start a new section. The .bank pseudo-instruction starts a new CODE section.
Example:
.code
... This does not start a new CODE section.
.bank 1
... This starts an absolute CODE section.
:
• If the .bank pseudo-instruction is defined immediately before a section definer (.code or .bss), it does
not start a new section and makes no effect to the following sections.
Example:
.code
... The latest relocatable section definition.
:
.bank 1
... This does not start a new absolute section and makes no effect.
.bss
... The another kind (BSS) of section which is not affected by the
:
previous ".bank" pseudo-instruction in the CODE section.
.code
... This will be an relocatable CODE section not affected by the
:
previous ".bank" pseudo-instruction.
