A12 is routed through 3 LS gates (from CHAROM) while CE only on 1. I'm almost sure the address is changing _after_ the CE was activated. Are you sure there are no hazads there? Using CHAROM twice on different levels looks not so good. Try more delay for OE/CE as a workaround. - -- -soci- -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iEYEARECAAYFAlBzvGkACgkQyBOVYiJltRZnvACfRkStOa30DWeqCxh2RrZ6mNdf NwwAoL+i2YLTOl69unyfnhjVG643oLEo =VxT5 -----END PGP SIGNATURE----- Message was sent through the cbm-hackers mailing listReceived on 2012-10-09 06:00:15
