Frame Header Word 2 contains following information
Value
Bit
Description
Buffer-Sizet 31..16
The Buffer Size field indicates the size of the total AFDX-Buffer entry in
bytes, including the buffer
header. Due to the burst capabilities of the Hardware, the AFDX- Buffer
entry size is aligned to 64
byte blocks.
Reserved 15..11 reserved
ATT
10
Add Transmit Timestamp
Logical '1’: If this bit is set additional to the FTI, then BIU-
Processor adds the corresponding
Timestamp of the FTI Event to the Interrupt Loglist Entry
FTI
9
Frame Transmitted Interrupt
Logical '1’: If this bit is set, the BIU- Processor asserts an interrupt,
if the current frame was physically transmitted and the Interrupt Loglist
Entry will include the start address of the current frame.
SND
8
Sequence Number Insertion Disable
Logical '1’: If this bit is set, the AFDX- Sequence Number insertion at the
end of the MAC- Frame
is suppressed.
Logical '0': Default, AFDX- Sequence Number insertion at the end of the
MAC- Frame.
SN
7…0
MAC- Frame Sequence Number for this packet. At packet
transmission, the Encoder add this
sequence number at the end of the AFDX- Frame, if the SND bit is not
set.
