6. INTERRUPT/EXCEPTION HANDLING FUNCTIONS
The features of the interrupt/exception handling functions are shown below.
• Interrupts
• Nonmaskable interrupt: 1 source
• Maskable interrupt: 32 sources
• 8-level programmable priority control
• Multiple interrupt control based on priority levels
• Mask specification for each maskable interrupt request
• Noise elimination, edge detection, and valid edge specification for external interrupt requests
• Exceptions
• Software exceptions: 32 sources
• Exception trap: 1 source (invalid instruction code exception)
The configuration of the interrupt/exception handling functions is shown below.
