15.1 Interrupt Function Types
15.2 Interrupt Sources and Configuration
15-1).
The following two types of interrupt functions are used.
(1)
(2)
A total of 17 non-maskable and maskable interrupts are incorporated as interrupt sources (see Table
Non-maskable interrupt
This interrupt is acknowledged unconditionally. It does not undergo interrupt priority control and is given top
priority over all other interrupt requests.
A standby release signal is generated.
One interrupt source from the watchdog timer is incorporated as a non-maskable interrupt.
Maskable interrupt
These interrupts undergo mask control. If two or more interrupts with the same priority are simultaneously
generated, each interrupt has a predetermined priority as shown in Table 15-1.
A standby release signal is generated.
Five external interrupt and 11 internal interrupt sources are incorporated as maskable interrupts.
