6.1 Decoder Buffer
The decoder will buffer 16 bytes in first-in-first-out order when the system is able to
read scan codes from RF receiver module. The response codes and repeated codes
will not be buffered. If receives a multiple-byte sequence, the entire sequence must fit
into the buffer or the key data is discarded and a buffer-overrun condition occurs.
