do you realy need to set it on an absolute address?
usualy just using
.text
is enough, the linker will move the code to somewhere in the available flash
otherwise try that:
http://sources.redhat.com/binutils/docs-2.15/as/Org.html#Org
mov.b #80h,&BCSCTL2 ; MCLK=DCOCLK/1, SMCLK=DCOCLK/1
mov #Calibr-$-6,R5 ; see below: Calibr: clr R12 ;
TimerA clear and start count up
does "$" work? if not:
http://sources.redhat.com/binutils/docs-2.15/as/Dot.html#Dot
assembler docs are here:
http://sources.redhat.com/binutils/docs-2.15/as/index.html
Any ideas?
By the way: In the listing file i can see that compilation places a
nop after every dint. In a c file there is no need to set a nop after a
dint.
the MCU does not care in which source language the program was written. ;-)
it will delay the effect of dint by one instruction, thus a nop has to
be used to be sure that ints are locked.
