hello:

 

i'm writiing some xdp512 assembler code to listen to the j1939 protocol. the protocol uses the 29 bit extended identifier and i want to use four sixteen bit identifiers.

 

after shifting the bits around the three flags imbedded is the 16 bit pattern from d0 to d15 or is it the upper 16 bits of the 29?

 

thanks in advance!!
