RE: [avr-gcc-list] Newbie Problems

[Panther Electronics]

hi,
 
a simple asm also lands in problems ;-(
 
a) the compiler wants the passed variables to be in Register above R15, this i 
belive is done by declaring the the inputs as "d" or "a" but doing so effects 
the 
b) cbi function it wants the passed vaiables in the range 0-63 "I"
 
what must i do so that the so that the passed variable is both "I" and also its 
loaded into Simple upper registers "a".
 
thanks in advance

from other list members, what am i doing wrong?
