[Number of bits required for SECDED]
I think he meant +1 instead of -1 in the equation. So
5 bits, not 3.
But I assumed that he'd just copied it wrong from memory or source.
OK, that makes a lot of sense, and I agree it's possible to do SECDED on
16 bit word with 5 'extra' bits, as indeed these Philips boards seem to
do. I couldn't see how to do it with onyl 3 extra bits, and indeed it
appears it can't be done.
It was not my intention to insult anyone, of course. But if somebody
posts something that I can't figure out, I will ask about it. Most of the
time I'll be the idiot for not being able to figure it out, but by having
it explained I'll learn something.
