Op-Code
Description
No-Op op-code. ARINC 429 word construction will be terminated and the
sequencer will move on to the next descriptor in the table.
No-Op op-code. ARINC 429 word construction will be terminated and the
sequencer will move on to the next descriptor in the table.
Immediate data. The value contained in the descriptor value data byte is
loaded into this byte position of the ARINC 429 32-bit message to be
transmitted.
Immediate data conditional. The NEWTXn bit corresponding to the ARINC
Data RAM location defined by channel “CCC” and label block “LLLLLLLL” is
read. LLLLLLLL is used if NEWTXn is set for this
conditional opcode
conditional op codes (within this descriptor frame) then no transmission
occurs for this frame and the sequencer increments to the next descriptor
frame. The NEWTXn bit for the referenced ARINC RAM block is reset.
Indexed data. The value of ARINC Data RAM location defined by channel
“CCC”, label block “LLLLLLLL” and byte number “BB” is loaded into this byte
position of the ARINC 429 label to be transmitted.
Indexed data conditional. The NEWTXn bit corresponding to the ARINC
Data RAM location defined by channel “CCC”, label block “LLLLLLLL” and
byte number “BB” is read. The corresponding byte is used if
NEWTXn is set for this
descriptor frame. If NEWTXn = 0 for all conditional op codes (within this
descriptor frame) then no transmission occurs for this frame and the
sequencer increments to the next descriptor frame. The NEWTXn bit for the
referenced ARINC RAM block is reset.
