Interrupt/Exception Processing Function
The V850E/PH2 microcontroller is provided with a dedicated interrupt controller (INTC) for interrupt
servicing, which realizes a high-performance interrupt function that can service interrupt requests from
a total of up to 107 sources.
An interrupt is an event that occurs asynchronously (independently of program execution), and an
exception is an event that occurs synchronously (dependently on program execution). Generally, an
exception takes precedence over an interrupt.
The V850E/PH2 microcontroller can process interrupt requests from the internal peripheral hardware
and external sources. Moreover, exception processing can be started (exception trap) by the TRAP
instruction (software exception) or by generation of an exception event (fetching of an illegal op code).
