Folks at Google call it "Hallucinating", I call it jive-ass lying.
I asked it an obscure technical question. I know the answer because the processor instruction I asked about was one I requested be included in the microcontroller. So, in a sense JACC is "my instruction".
The description at first looks plausible, but it is actually quite incorrect.
The chatGPT session:
Me: What is a JACC instruction in a Cypress M8C microcontroller?
ChatGpt: I apologize for the confusion earlier. The JACC instruction is a jump with automatic condition code update instruction in the assembly language of the Cypress M8C microcontroller.
The JACC instruction is used to jump to a specific memory location if a particular condition is true, while also automatically updating the condition code flags in the process. The condition code flags are used to indicate the outcome of the most recent arithmetic or logical operation, and can be tested to control the flow of program execution.
The syntax for the JACC instruction in M8C assembly language is as follows:
sql
JACC condition, target
Here, condition is a test that is performed on the condition code flags, and target is the address of the memory location to jump to if the condition is true.
For example, the following code snippet demonstrates the use of the JACC instruction to jump to a specific memory location if the carry flag is set:
css
ADD A, B ; perform some arithmetic operation
JACC CY, target ; jump to target if carry flag is set
If the carry flag is set as a result of the previous ADD operation, the JACC instruction will jump to the target memory location. Otherwise, program execution will continue with the next instruction.
