DGROUP Assembler Statement

Arguments
group DGROUP section <[>, section ...<]>
Description

The DGROUP statement defines a group of data sections where group is the name of the group to define and sections are the sections to add to the group.

A data group may contain a dummy section named SYSTEM which covers the internal Special Function Register (SFR) area. The SYSTEM section serves as a placeholder for the SFR area (because SFRs are not defined using ordinary section directives).

Note

  • Data groups may not exceed 16K Bytes in total size and may only contain data sections.
  • Data groups are located as one logical unit to a 16K Byte page.
  • The order of sections in a group may change after linking.
  • If one section in the group is absolute, the group is absolute. The order of sections within that group depends on the absolute section.
