5.2.6: Flash Interrupts

The _CPU_ISR_Flash routine temporarily restores the interrupt to _level before immediately disabling them again. This is used to divide long RTEMS critical sections into two or more parts. This routine is always preceded by a call to _CPU_ISR_Disable and followed by a call to _CPU_ISR_Enable. The parameter _level is not modified.

The following is a dummy implementation of the _CPU_ISR_Flash routine:

#define _CPU_ISR_Flash( _isr_cookie ) \
  { \
  }

The following is the implementation from the Motorola M68K port:
