MC68060 TT Behaviour

[bigbloke]

Might be worth looking at a small delay in the CLKEN* generation. Page 11-14 of the (NXP) 68060 datasheet has an example if migrating from 68040, and although doesn't explicitly state it, all diagrams show a 5ns delay on the clk divide by 2 to make CLKEN*

Sorry if you already seen/do this. I'm still picking up 68xxxx from when I last touched it in the 90s!

Yeah i've tried a bunch of delay types. :/

OK i think something else is happening. Because TT signal was a measurement error.

I was going to ask what it looks like without the CLKEN toggle, but it was just a ghost, was it?

Actually wasnt measuring TT... its a quirk of the LA. I'll need to figure out whats really going on
