I'm sorry if this is a silly question... but how do you tell the system which 8 bit is the first and which is the second 8 bit? The way i see your suggestion is that, use a counter to count until 8 bits then send the 8 bits to something. then the last 8 bits also are counted and sent to the next process.
The signal i need to transmit is continuous 16 bit signal, which means that after the current 16 bit signal, there is also other 16 bit signal coming, and there is also another 16 bit signal behind that. so one 16 bit signal contains one information.
