bogdanm 0:9b334a45a8ff 46 * This module contains functions to safely disable and enable interrupts
mbed_official 50:a417edff4437 47 * at CPU level. INT_Disable() disables interrupts globally and increments a lock
mbed_official 50:a417edff4437 48 * level counter (counting semaphore). INT_Enable() decrements the lock level
mbed_official 50:a417edff4437 49 * counter and enable interrupts if the counter reaches zero.
bogdanm 0:9b334a45a8ff 50 *
mbed_official 50:a417edff4437 51 * These functions would normally be used to secure critical regions, and
mbed_official 50:a417edff4437 52 * to make sure that a critical section that calls into another critical
mbed_official 50:a417edff4437 53 * section does not unintentionally terminate the callee critical section.
bogdanm 0:9b334a45a8ff 54 *
bogdanm 0:9b334a45a8ff 55 * These functions should also be used inside interrupt handlers:
