## 4.5.3 Interrupt Code

For the interrupt function, use the keyword '__interrupt' with level number of 0 (PIC14 only has 1 interrupt so this number is only there to avoid a syntax error - it ought to be fixed). E.g.:

> `void Intr(void) __interrupt 0`
> `{`
> `T0IF = 0; /* Clear timer interrupt */`
> `}`
