Cyg_Interrupt::Cyg_Interrupt
(
  cyg_vector   vector,   /* Interrupt vector          */
  cyg_priority priority, /* queue priority            */
  CYG_ADDRWORD data,     /* data pointer              */
  cyg_ISR      *isr,     /* interrupt service routine */
  cyg_DSR      *dsr      /* deferred service routine  */
)

The isr has the prototype of cyg_uint32 cyg_ISR(cyg_vector vector, CYG_ADDRWORD data). The ISR is called from the VSR. The VSR is usually implemented by eCos itself. If the ISR returns Cyg_Interrupt::HANDLED the VSR will NOT be called, if the ISR returns Cyg_Interrupt::CALL_DSR the VSR is called.

The vsr has the prototype of void cyg_DSR(cyg_vector vector, cyg_ucount32 count, CYG_ADDRWORD data). The DSR returns nothing.

ISR's cannot access the vast majority of kernel routines. The VSR can access more routines. What can and cannot be called safely from these routines I have not found in the documentation yet.
