Interrupts

17 Internal interrupts

 

<Non-maskable interrupt (NMI)>

- Incorrect code execution interrupt and Watchdog timer interrupt < Timer interrupts >

- Timer 0 interrupt (8-bit timer) - Timer 1 interrupt (8-bit timer) - Timer 4 interrupt (8-bit timer) - Timer 5 interrupt (8-bit timer) - Timer 6 interrupt (8-bit timer)

- Time base interrupt (8-bit timer) - Timer 7 interrupt (16-bit timer)

- Match interrupt for Timer 7 compare register 2
