5.2.5: Enable Interrupts

The _CPU_ISR_Enable routines enables interrupts to the previous level (returned by _CPU_ISR_Disable). This routine is invoked at the end of an RTEMS critical section to reenable interrupts. The parameter _level is not modified but indicates that level that interrupts should be enabled to. The following illustrates a dummy implementation of the _CPU_ISR_Enable routine:

#define _CPU_ISR_Enable( _isr_cookie )  \
  { \
  }

The following is the implementation from the Motorola M68K port:
