Putting some Visual 6502 links here so I don't lose them:
Smallest IRQ assertion interval that will trigger an IRQ for LDA #FF: http://visual6502.org/JSSim/expert.html?logmore=Execute,irq&a=0&d=58A9FF1890FE&irq0=5&irq1=6&steps=20
Ditto for LSR $AB: http://visual6502.org/JSSim/expert.html?logmore=Execute,irq&a=0&d=5846AB1890FE&irq0=11&irq1=12&steps=20
Ditto for LSR $AB with NMI instead of IRQ: http://visual6502.org/JSSim/expert.html?logmore=Execute,nmi&a=0&d=58461890FE&nmi0=11&nmi1=12&steps=20
