The most typical and general program setup for the reset and interrupt vector addresses
for the ATtiny11 are:
Address Labels Code Comments
$000 rjmp RESET ; Reset handler
$001 rjmp EXT_INT0 ; IRQ0 handler
$002 rjmp PIN_CHANGE ; Pin change handler
$003 rjmp TIM0_OVF ; Timer0 overflow handler
$004 rjmp ANA_COMP ; Analog Comparator handler
;
$005 MAIN: <instr> xxx ; Main program start
