5-1 

5.  Interrupts  

5.1  Overview 

This LSI has 13 interrupt sources (External interrupts: 4 sources, Internal interrupts: 9 sources) and a software interrupt 
(SWI). 
For details of each interrupt, see the following chapters: 

Chapter 7, “Time Base Counter” 
Chapter 9, “Timer” 
Chapter 10, “Watchdog Timer” 
Chapter 11, “UART” 
Chapter 12, “Port 0” 
Chapter 17, “RC Oscillation Type A/D Converter” 

 

5.1.1  Features 

•

    Non-maskable interrupt source: 1 (Internal sources: 1) 

•

    Maskable interrupt sources: 12 (Internal sources: 8 , External sources: 4) 

•

    Software interrupt (SWI): maximum 64 sources

 

 

•

    External interrupts allow edge selection and sampling selection
