OBC insert
The first byte indicates the SOP or EOP and also whether the packet is error tagged or not by writing into the ED bit. The second byte is the lid
information, which tells the OBC controller, which lid the packet goes to. The 3rd byte is the length of the packet in bytes. After this overhead is written,
the packet is written into the OBC insert locker, not to exceed 256 bytes. If the packet length exceeds 256 bytes, then the first 256 bytes is written into
the locker, transferred to the PFP and when the locker is empty, the remaining bytes of the packet is written into the insert locker. The pseudo code is
given below.
Begin: Is {packet_length > 256}
if yes {set flag = (SOP = 1 << 7) || (EOP = 0)} else {set (SOP = 1 << 7) || (EOP = 1)}
if yes {set length = 256} else { set length = packet_length}
Direct Read DATA_AVAILABLE flag in PFP T-M insert control register (Register Offset=0x0) (p. 96) // Availability of OBC insert FIFO
if {result = 0}
write packet_data to PFP T-M insert data register(Register Offset=0x1) (p. 97) //if length >256, write 256 bytes in run1.
// to launch data. This causes data to be read into the PFP and
//clear the FIFO and setting the DATA_AVAILABLE bit to 0.
if {packet_length>256} {
set remaining_length = packet_length - 256
set packet_length = remaining_length
goto Begin
