Documentation suggestion

Hi CF people. I'm trying to use the datasheet for the CFA-635 with SCAB (PDF version 1.4) and I'm getting some progress. Here are some suggestions which IMHO would make the doc more user-friendly.

Stick to either decimal or hex (preferred) when listing the command codes. As an example: the docs say on success command code 19 (decimal) should report back 0x40 | 19. To interpret that in my head, it's either convert 19 to hex then bitwise or that with 0x40; or convert 0x40 to decimal and sum the two. It just means a little more complication than is necessary to work with the display.

Also, how about putting one command code per page - I can't see you printing a huge number of these and it makes things much clearer. I know it would be wasteful should anyone ever print this out, but in my copy several commands are split over two pages.

Thanks in advance,

Ian.

Also, I think that the spec is wrong for the temperature sensor report (0x82): I think data[1] is LSB and data[2] is MSB. The algorithm works because Intel machines are little-endian.

Thank you for your suggestions. I will suggest the changes. I think there is a good chance the hex/decimal could happen, but the pagination probably willl not.

Same for the fan speed report data. data[2] is LSB and data[3] is MSB.
