So what this means is that to get the command/data bit we use: first_byte & 0x80 If that is correct I will remove this patch from the series and will update the subsequent patches so bit 7 is the command bit, bit 6 is reserved, and bits 0-5 are the pad length. I will post a v2 of the series with these changes, and will incorporate Bjorn's "Reviewed-by". -Alex
