A166: Error A74 (Operand Type Mismatch)

Information in this article applies to:

  • A166 Version 4.20


In an A166 project if I do:

 subcb MyReg, 0x1234     ; gives Operand Type Mismatch error

but if I do:

addc  MyReg, 0x1234     ; ok

I receive the error A74 operand type mismatch. How can I resolve this problem?


This problem is corrected in C166 V4.22. You may download the latest updates from the Keil Website.
