17.1 Features
668
The V850E/IA3 and V850E/IA4 are provided with a dedicated interrupt controller (INTC) for interrupt servicing and
An interrupt is an event that occurs independently of program execution, and an exception is an event whose
The V850E/IA3 and V850E/IA4 can process interrupt requests from the on-chip peripheral hardware and external
Interrupt sources are listed in Table 17-1.
Interrupts
• Non-maskable interrupts: 1 source (external: none, internal: 1 source)
• Maskable interrupts (the number of maskable interrupt sources differs depending on the product)
• 8 levels of programmable priorities (maskable interrupts)
• Multiple interrupt control according to priority
• Masks can be specified for each maskable interrupt request.
• Noise elimination, edge detection, and valid edge specification for external interrupt request signals.
Exceptions
• Software exceptions: 32 sources
• Exception traps:
V850E/IA3: 55 sources (external: 7 sources, internal: 48 sources)
V850E/IA4: 60 sources (external: 8 sources, internal: 52 sources)
Moreover, exception processing can be started by the TRAP instruction (software exception) or by
