Question:
When an interrupt request occurs during unlocking key code protection of I/O port, will the key code protection be unlocked after the interrupt processing?
Answer:
If an interrupt processing contains I/O port access, unlocking process will fail. You need to handle unlocking key code protection again or disable the interrupt during unlocking key code protection.
If an interrupt processing does not contain I/O port access, key code protection is unlocked after the interrupt processing.
