dp256b errata - Michael Huslig - Feb 1 10:18:00 2005

Gentlemen,

If I remember right, the 9S12DP256B was supposed to have the SCI
odd-number-of-interrupts bug fixed, but now there is a new errata sheet for
the part that says it is still a problem. Am I remembering right?

Mike

Hello,

NO, there are:

1) MC9S12DP256B, mask set 1K79X (SCI bug MUCts00510 available, not
fixed)
http://www.freescale.com/webapp/sps/site/prod_summary.jsp?
code=MC9S12DP256B

2) MC9S12DP256C, mask set 2K79X (SCI bug MUCts00510 fixed)

3) MC9S12DT256, mask sets 3L91N,4L91N, ... (SCI bug MUCts00510
fixed) - this microcontroller is recommended for the new designs!

You are right. But there's not a new errata sheet. It is the same one
for specific mask sets.

Re: Re: dp256b errata - Michael Huslig - Feb 1 15:18:00 2005

But the DP256C is still not listed among the HCS12s at the regular freescale
site. ----- Original Message -----
