actually this code is correct !0x02 -> 0 while ~0x02 -> 0xFD

Hi!
I think both of the lines below should create the same code, but it's
not what can I'm seing. Below is an extract of a .lst file. It's
compiled with the win build 20030506. and compiler options
"-mmcu=msp430x1232 -O2 -Wall -g"
Thanks,
Ricardo.

U0IFG &= 0xFD;
