==== <code>DI</code> ====
: Disables interrupts (but not[ESC]) until re-enabled by EI command or by RETURN at end of an interrupts service routine.
: This means that DI (if it's activated in a subroutine) is useful helping a low-priority-interrupt not to be stopped by a higher-priority-interrupt. RETURN then re-enable the interrupt without EI.
