Figure 9.1.1 shows types of interrupts.
NOTES:
• Maskable Interrupt: An interrupt which can be enabled (disabled) by the interrupt enable flag (I flag) or
• Non-maskable Interrupt: An interrupt which cannot be enabled (disabled) by the interrupt enable flag

1. Peripheral function interrupts are generated by the microcomputer's internal functions.
2. Do not normally use this interrupt because it is provided exclusively for use by development tools.
The 42-pin package does not use UART0 transmission interrupt and UART0 reception interrupt of
peripheral function.
M16C/26T does not use voltage down detection interrupt.
