Applies to: BL51 Code-banking Linker/Locator
Answer
Information in this article applies to:
- C51 Version 6.01
QUESTION
What does the NOJMPTAB directive do?
ANSWER
Use the NOJMPTAB directive (abbreviated NOJT) to direct the BL51 code banking linker/locator not to insert the inter-bank call table used for code banking. This directive is provided to enable you to create your own user-defined bank switching mechanism.
The NOJMPTAB directive modifies the behavior of BL51 as follows:
- The L51_BANK.OBJ banking logic is no longer required.
- Call instructions are not modified to jump to the call table.
- Warnings are not generated if a jump or call is made to another bank.
When you use NOJMPTAB, you must ensure that the proper bank is selected before you invoke a function in that bank. The BL51 code banking linker does not select the bank automatically.
MORE INFORMATION
- Refer to NOJMPTAB in the BL51 User's Guide.
