Now that A stepping CPUs start dying out, could we not switch the reset mechanism to use LDTSTOP instead of a complete reset? It's more solid and a lot faster.
Solid? There are several errata with using LDTSTOP and you can not use it after memory is initialized.
We don't do this anyways, do we? In situations with marginal timing for RESET#, there is less chance of something going wrong. Hardware is rarely perfect, and LDTSTOP# affects less of it, so it is a little more robust. Stefan
