If an interrupt condition occurs when the corresponding interrupt enable bit is cleared (zero),
the interrupt flag will be set and remembered until the interrupt is enabled, or the flag is
cleared by software.
If one or more interrupt conditions occur when the global interrupt enable bit is cleared (zero),
the corresponding interrupt flag(s) will be set and remembered until the global interrupt enable
bit is set (one), and will be executed by order of priority.
Note that external level interrupt does not have a flag, and will only be remembered for as long
as the interrupt condition is active.
