Interrupts #1
Description
There are only five interrupt sources:
| Interrupt Source | Handler address |
|---|---|
| V-blank | 0x0040 |
| LCD STAT | 0x0048 |
| Timer | 0x0050 |
| Serial | 0x0058 |
| Joypad | 0x0060 |
Interrupt support needs to be added to the CPU, and it doesn't necessarily depend on the implementation of these devices. An Interrupt Flag register can be added to the MMU that indicates an interrupt request. The CPU can check this register before the fetch stage.
