ATmega329PA interrupt vectors

The 23 vectors at the start of flash, two words each (a JMP). A lower number has the higher priority; vector 0 is reset. In avr-gcc a handler is ISR(NAME_vect).

Vector	Program address	Name	Handler	Source
0	`0x0000`	RESET	reset: `main()` after start-up	External Pin,Power-on Reset,Brown-out Reset,Watchdog Reset,and JTAG AVR Reset. See Datasheet.
