Hi everybody!
I need informations about interrupts of the Plus4. How do the FF09 and FF0A work exactly?
When does the hardware set the 7th bit of FF09? What happens exactly when the mask disables an interrupt and it occurs?
And what happens if a request bit is set, but its interrupt occurs again? Is it possible?
If you have some very detailed information, help me! Thanks!
Greetings,
Zsolt
