Model FDS transfers as controller-driven byte events, separating timer IRQs, data service, motor state, CRC, BIOS sequencing, and uncertain acknowledgements.
Reproduce the HuC6280's seven-bit interval timer, oscillator prescaler, reload edge, interrupt request flag, and counter-read caveat in PC Engine software.
Use the AT-compatible RTC periodic and alarm sources without racing BIOS timekeeping, losing status flags, or leaving IRQ8 and CMOS state misconfigured.
Map Linux MSI-X queue interrupts to CPUs safely by distinguishing requested from effective affinity, managed IRQ rules, hotplug, and NUMA locality.
