0 = Priority level 0 for ADC interrupt.
1 = Priority level 1 for ADC interrupt.
Note : The priority level 0 means the low priority interrupt level. And,
0 = Priority level 0 for serial port interrupt.
1 = Priority level 1 for serial port.
0 = Priority level 0 for timer1 interrupt.
1 = Priority level 1 for timer1 interrupt.
0 = Priority level 0 for external interrupt 1.
1 = Priority level 1 for external interrupt 1.
0 = Priority level 0 for timer0 interrupt.
1 = Priority level 1 for timer0 interrupt.
0 = Priority level 0 for external interrupt 0.
1 = Priority level 1 for external interrupt 0.
