CHAPTER 5 INTERRUPT/EXCEPTION PROCESSING FUNCTION

The V854 is provided with a dedicated interrupt controller (INTC) for interrupt processing and can process a total

of 32 interrupt requests.

An interrupt is an event that occurs independently of program execution, and an exception is an event that occurs

dependently on program execution. Generally, an exception takes precedence over an interrupt.

The V854 can process interrupt requests from the internal peripheral hardware and external sources. Moreover,

exception processing can be started by the TRAP instruction (software exception) or by generation of an exception

event (fetching of an illegal op code).

5.1 Features

Interrupt

• Non-maskable interrupt: 1 source

• Maskable interrupt: 31 sources

• 8 levels programmable priorities control

• Multiple interrupt control according to priority

• Mask specification for each maskable interrupt request

• Noise elimination, edge detection, and valid edge of external interrupt request signal can be specified.

Exception

• Software exception: 32 sources

• Exception trap: 1 source (illegal op code exception)

Interrupt/exception sources are listed in Table 5-1.
