Note: 1.
All action must send first byte to wake up CPU and receive 06(ACK) from CPU, then you can begin to send again.
2.
When sending IR code data, nn mean device number 1=TV 2=VCR 3=CBL 4=AUX.
3.
When sending IR code data 60 bytes,each byte CPU will send back 06(ACK) for hand shaking.
4.
To stop AUTOSCAN,you must send 90 to stop,then you willl receive 1 byte of code number from CPU.
