Re: I've got the EEC Software Manual and Custom IC Hardware Architecture Reference

Can we configure a wildcard SSL certificate for the site:

As the current cert is only for eectuning.org, I still get a certificate error if I visit https://www.eectuning.org. A cert for *.eectuning.org would fix it.

Re: Execute Enable Register?

So is it accessed via the DAR like other RAM contents?

It sounds like you're saying that normally if you use the RAM's SPC to read, it probably just floats the bus and you get 0xFF's unless the EER was written 0xAA.

Please confirm my ignorance or deny my understanding :lol:
