7. INTERRUPT FUNCTIONS
7.1
Interrupt Function Types
Two types of interrupt function are supported.
(1) Nonmaskable interrupt
A nonmaskable interrupt request is accepted unconditionally, that is, even when interrupts are disabled. A
nonmaskable interrupt takes precedence over all other interrupts; it is not subjected to interrupt priority control.
A nonmaskable interrupt causes the standby release signal to be generated.
The
μ
PD789186,
μ
PD789187,
μ
PD789196, and
μ
PD789197 support one nonmaskable interrupt source namely,
the watchdog timer interrupt.
(2) Maskable interrupt
Maskable interrupts are those which are subjected to mask control. If two or more maskable interrupts occur
simultaneously, the default priority listed in Table 7-1 applies.
The maskable interrupts cause the standby release signal to be generated.
The maskable interrupts supported by the
μ
PD789186,
μ
PD789187,
μ
PD789196, and
μ
PD789197 include 4
external interrupt sources and 14 internal interrupt sources.
7.2
Interrupt Sources and Configuration
The
μ
PD789186,
μ
PD789187,
μ
PD789196, and
μ
PD789197 each support a total of 19 maskable and
nonmaskable interrupt sources. (See
Table 7-1
.)
