62 =2 * Method #2: Disable/Enable interrupts by preserving the state of interrupts. In other words, if
63 =2 * interrupts were disabled before entering the critical section, they will be disabled when
64 =2 * leaving the critical section.
65 =2 *
66 =2 * Method #3: Disable/Enable interrupts by preserving the state of interrupts. Generally speaking you
67 =2 * would store the state of the interrupt disable flag in the local variable 'cpu_sr' and then
68 =2 * disable interrupts. 'cpu_sr' is allocated in all of uC/OS-II's functions that need to
69 =2 * disable interrupts. You would restore the interrupt disable state by copying back 'cpu_sr'
70 =2 * into the CPU's status register.
