Interrupt — R/WC. Software can use this bit to determine if an IDE device has asserted its interrupt
line (IRQ 14 for the Primary channel, and IRQ 15 for Secondary).
0 = Software clears this bit by writing a 1 to it. If this bit is cleared while the interrupt is still active,
1 = Set by the rising edge of the IDE interrupt line, regardless of whether or not the interrupt is
Error — R/WC.
0 = Software clears this bit by writing a 1 to it.
