*1 Peripheral I/O interrupts are generated by the peripheral functions built into the microcomputer
system. High-speed interrupt can be used as highest priority in peripheral I/O interrupts.
Figure 1.9.1. Classification of interrupts
• Maskable interrupt
• Non-maskable interrupt
: An interrupt which can be enabled (disabled) by the interrupt enable flag (I
flag) or whose interrupt priority can be changed by priority level.
: An interrupt which cannot be enabled (disabled) by the interrupt enable flag
(I flag) or whose interrupt priority cannot be changed by priority level.
