16* | command | address |
17* SIRC | 7b LSB | 5b LSB |
18* SIRC15 | 7b LSB | 8b LSB |
19* SIRC20 | 7b LSB | 13b LSB |
20*
21* No way to determine either next message is repeat or not,
22* so recognize only fact message received. Sony remotes always send at least 3 messages.
23* Assume 8 last extended bits for SIRC20 are address bits.
