4. INTERRUPT/EXCEPTION HANDLING FUNCTIONS
The V821 features an interrupt controller (ICU) that is dedicated to interrupt handling. The V821 thus supports
a powerful interrupt handling function capable of handling interrupt requests issued by up to 16 sources.
As referred to in this manual, an interrupt is an event which occurs independently of program execution while an
exception is an event that depends on program execution. In general, an exception assumes a higher priority than
an interrupt.
The V821 can handle interrupt requests issued by both built-in peripheral hardware and external devices.
Exception handling can be triggered by executing an instruction (TRAP instruction) as well as by the occurrence of
an exception (such as an address trap or invalid instruction code).
4.1 Features
Interrupts
Nonmaskable interrupt : 1 source
Maskable interrupt
Programmable priority control with four groups
Multiple interrupt handling control according to priority
Mask specification for each maskable interrupt request
The noise eliminator introducing an analog delay (60 to 300 ns) is incorporated into the nonmaskable
interrupt (NMI) pin.
: 15 sources
Exceptions
Software exception: 32 sources
Exception trap
: 10 sources
Table 4-1 lists the interrupt and exception sources.
