CHAPTER 6 INTERRUPTS
CHAPTER 6 INTERRUPTS
V830 interrupts include maskable interrupts, nonmaskable interrupts, and reset operations.
6.1 MASKABLE INTERRUPTS
Maskable interrupt requests are themselves denoted by INT, and their interrupt levels by INTV0 to INTV3.
The following lists pin states and the corresponding interrupt levels.

INT and INTV0 to INTV3 are level inputs. The V830 samples an INT at the rising edge of a bus clock
pulse. INT and INTV0 to INTV3 should be held at the active level until the V830 accepts the interrupt request
and posts to a peripheral, by software, notification of the acceptance of the interrupt request. Although a
change to a higher interrupt level is possible, the timing at which an interrupt request is detected cannot then
be posted to peripheral.
Hence, an interrupt request made before such a change may be accepted. If the interrupt request input
(INT, INTV0-INTV3) fails to satisfy the setup time requirement for the bus clock pulse, the interrupt request
will be detected at the rising edge of the next bus clock pulse.
