PRIORITY - The priority for the sRIO packet header. CR is set to zero and ignored as part of the priority.
Default priority should be 00h, low priority.
TT - The sRIO transaction type. If set to 00h, the transaction is 8 bits, if set to 01h, the transaction is 16
bits. Other TT values are invalid.
FTYPE - Defined in the sRIO specification, part 1, section 4.1. The only FTYPEs supported are types 5
(WRITE) and 6 (SWRITE).
TARGET ADDRESS - The destination ID for the packet to be sent. This byte will be included in all
packets using this case scenario.
TARGET ADDRESS, x16 - The MSB of the address if the sRIO transaction is 16 bits. If TT = 00, the
target address MSBs are used.
TTYPE - The sub transaction to the FTYPE defined in the same location as FTYPE. If FTYPE is 5 the
only TTYPEs supported are NWRITE and NWRITE_R.
The size is set by the hardware and should not be part of the case scenario. See sRIO spec., section
4.1.2.
