This might be an odd question on an old processor, but I have written an emulation of a Heathkit ET-3400A microcomputer trainer in Java. I was adding the ability to trigger interrupts, and the Motorola 6800 datasheet indicates the I flag (interrupt mask) is set at reset. The 6800 programmer's reference, however, has a passage that indicates it is cleared at reset. Anybody know which one it is?
Because this is not an MC6800 specific question, but it is about all documents from the 1990s and earlier, I will answer here and not on retrocomputing.stackexchange.com:
... if the interrupt mask bit is in the reset state ...
Until the 1990s, the word "reset" typically meant what we would call "cleared" today.
In some contexts (for example "RS-Flip-Flops") the word "reset" still means "cleared" (and not: "initial state") today!
So the text in the Programmer's Manual actually means:
... if the interrupt mask bit is in the cleared state ...
