10.1 Interrupt Overview
Interrupt
• 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
NOTES:
1. Peripheral function interrupts are generated by the peripheral functions built in the microcomputer system.
2. Avoid using this interrupt because this is a dedicated interrupt for development support tools only.
