Returns Nothing
The interrupt priority in the status register (SR) is set to 6 to disable
interrupts or reset to 0 to enable interrupts.
Restrictions ISPs must not use cjcfei. If nested interrupts are supported in your
application, ISPs must always use cjcfflagwr to restore interrupts to the
state determined by an earlier call to cjcfflagrd.
Interrupts should be enabled within a short time after they are disabled or
system performance will be degraded.
