The IC ST16C554D combines the package interface modes of the 16C554 and 68C554 series on a single integrated chip.

Thats an electrical signal difference not an interface one as I understand it (beyond the fact it might change the register offsets depending how the board was wired) I don't think it matters therefore. -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
