This register sends an sRIO doorbell on S-Port and is not capable of generating an interrupt on Int 0 or Int 1, therefore
If this register generates an sRIO packet, the packet will be a doorbell.
If missing 2 packet is turned on and two or more packets are missing, this register will allow a programmable doorbell to
If this register generates an sRIO packet, the packet will be a doorbell.

This flag is identical to the flag in the "sRIO DMA Status Information" register.
This is the destination ID for the DSP that must receive the tally indication doorbell. It is not required that
this be the same destination as in the "sRIO DMA Status Information" register.
The doorbell is turned on and off by masking bit 1.
The content of the doorbell is a 16 bit user programmable pointer.
