Explore Z80 assembly programming with a focus on interrupt handling in this comprehensive 37-minute video lesson. Dive into the "Template Interrupt Handler" that supports both Interrupt Mode 1 and 2, offers register protection options, and demonstrates safe stack manipulation techniques without disabling interrupts. Learn about returning to BASIC, implementing safety locks, and platform-specific code considerations. Examine shadow stack usage, including examples, corruption risks, and restrictions. Understand when to disable interrupts and scenarios where interrupts cannot occur. Follow along with sample code, practical examples, and testing procedures. Access accompanying text lessons and source code from the provided website link for a complete multiplatform learning experience in Z80 assembly programming.
