Information in this article applies to:

• C166

QUESTION

How can I relocate a register bank to another location in on-chip RAM? I have tried the following:

SECTIONS(myreg%REG (0xFD00))
SECTIONS(myreg%*REG* (0xFD00))

but they both give errors stating the section or register bank cannot be found.

ANSWER

You can relocate a register bank using the L166 REGBANK directive. For example, to relocate the register bank myreg to FD00H you would use:

REGBANK(myreg(0xFD00))

To set this directive in µVision:

• Choose Options for Target from the Project menu
• Click on the L166 Misc tab

• Enter

  myreg(0xFD00)
  

  into the RegBank box
