IDT 80KSBR200
Notes
Advanced Datasheet*
This register sends an sRIO doorbell on S-Port and is not capable of generating an interrupt on Int 0 or Int 1, therefore
there is no register number.
Name: CS0_TALY_DBEL_FLAG Address: 0x19E10
CS0_TALY_DBEL_MASK
0x19ED0
If this register generates an sRIO packet, the packet will be a doorbell.

Table 93 Tally Doorbell Flag Register
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.
8.5.11 Missing 2 Packet Programmable Flag Register
If missing 2 packet is turned on and two or more packets are missing, this register will allow a programmable doorbell to
be sent to a designated sRIO destination ID. Note that If this register is read and cleared, the “Missing Packet Address
Logging Register 2” will also be cleared.
