[ASM] can this be done differently? It's not the perfect way? notLow: cpi Y, 8 breq loEight brlo loEight ;if Y > 8, subi Y, 8 ; -> Y - 8 rjmp notLow loEight: Is there a shorter and better way to do this? |

RC=8MHz, ADCclock 4MHz, t=3.25usec? Is this correct. An ATtiny26 running @ 8MHz internal oscillator, ADCclock = 4MHz (clk/2) Does this mean one conversion takes 3.25 usec? (13ck/4MHz) |
