    Yes, bit 7 of the R register is used as an interrupt flag. And because LD A,R automatically sets the FLAG Register (you needn't test A at all) it's fast and ideal for sound loops.

  • When would you use LD A,R ?Can anyone tell me a practical use of LD A,R and LD R,A I am confused when you would need to use it? Cheers

    Fast flag using bit 7 (that doesn't change with the auto-increment). Frobush uses it in his sound routines, modifying bit 7 in the interrupt routine, and checking that bit every little while in his sound routines so the game continues after the interrupt.
