Struct gba_hal::data::InterruptRequestFlags

#[repr(transparent)]
pub struct InterruptRequestFlags(_);

Interrupt Requested Flags. GBATEK IF register.

This has the same bit layout as the InterruptEnable type, but this type is used to either check what interrupts are pending (IRQ_PENDING) or acknowledge an interrupt as processed (IRQ_ACKNOWLEDGE).

It may seem strange, but to acknowledge an interrupt as having been processed, you need to set that bit (and only that bit), even though it's already an active bit.

The full story of how to do interrupt handling properly is beyond the scope of this comment, but that's the basics.
