BL51: ERROR 121 (IMPROPER FIXUP)

Information in this article applies to:

• C51 All Versions

QUESTION

Help. I'm using the 8051 tools and I am getting the following linker error:

*** ERROR L121: IMPROPER FIXUP

The segment and offset indicate a clear bit and set bit instruction. What's wrong?

ANSWER

This is caused by an invalid address for the bit. The address used is outside of the bit addressable area.

For BIT variables, the address must be between 0x20 and 0x2F inclusive.

For SFR variables that are bit-addressable, the address must end in 0 or 8.
