AW: [avr-gcc-list] SPI2X in SPSR more explanation

[krystian.hirsch]

OK I am working with JTAG ICE (real HW) and self made mega16 board.
I can not set this bit neither from code e.g. :
SPSR|=0x01;
nor
SPSR|=(1<<SPI2X);
nor equivalent

Unlike for other bits in I/O workspace window, clicking on this bit is for no 
avail too. After next debugging step (or refreshment acitivies) it keeps to be 
reset to 0. So it is µC issue or AVRStudio issue rather than gcc issue.

What exactly do you mean by "I cannot set the SPI2X bit"? Are you using
the AVR Studio 4.x simulator?

You'll have to provide more details.
