Notes
tical to the START ADDRESS. The address will increment by the quantity of data transmitted with every packet. The NEXT
ADDRESS will not rise beyond the STOP ADDRESS. If the Wrap or Stop bit in the following register is set to WRAP, the
NEXT address will reset to the START ADDRESS whenever STOP ADDRESS has been hit. If the wrap occurs in the
middle of the packet, the NEXT ADDRESS will increment after the reset to indicate how much of the tail of the packet was
written after the wrap.
Case Scenario Stop Address Register
cases the packet length may cause a write to an address higher than this value, in case of an overflow. The START
ADDRESS and STOP ADDRESS should be identical if the user does not want the address issued in the packet header to
increment.
Case Scenario Frame Register

The current value for the ADDRESS. Whenever a new case scenario is programmed, this value will be set to be iden-
The final incremental address for writing. The higher address may be included in the sRIO packet header, but in some
