Core functions to enable/disable interupts globally. This is splitted from the
ruspiro-interrupt crate to remove circular dependencies between
the interrupt crate others (e.g. ruspiro-singleton) crate.
| disable_fiq | globally disable FIQ interrupts from beeing triggered. This function stores the state of the current enabling/disabling
of interrupts. If disable is called multiple times after each other this will than ultimately store "disabled" as
last state. In this case a previous enabled state (before the multiple calls) is not able to recover with a call to re_enable_fiq.
|
| disable_interrupts | globally disabling interrupts (IRQ/FIQ) from beeing triggered
|
| disable_irq | globally disable IRQ interrupts from beeing triggered. This function stores the state of the current enabling/disabling
of interrupts. If disable is called multiple times after each other this will than ultimately store "disabled" as
last state. In this case a previous enabled state (before the multiple calls) is not able to recover with a call to re_enable_irq.

| enable_fiq | globally enable FIQ interrupts to be triggered
|
| enable_interrupts | globally enabling interrupts (IRQ/FIQ) to be triggered
|
| enable_irq | globally enable IRQ interrupts to be triggered
|
| re_enable_fiq | globally re-enabe FIQ interrupts to be triggered based on the global state that was set before disabling FIQ
interrupts wihin the disable_fiq function.
|
| re_enable_interrupts | globally re-enabling interrupts (IRQ/FIQ) to be triggered. This is done based on the global state
that was set before the interrupts were disable using the disable_interrupts function.
|
| re_enable_irq | globally re-enabe IRQ interrupts to be triggered based on the global state that was set before disabling IRQ
interrupts wihin the disable_irq function.
