RC-6 Mode 0 and Mode 6A is briefly describe here:

http://www.picbasic.nl/frameload_uk.htm?http://www.picbasic.nl/rc5-rc6_transceiver_uk.htm

That page is slightly wrong, as there is some data coded in the header
such as the RC-6 Mode.

This page is an older version of the sbprojects.com RC-6 page, before
the information on RC-6 Mode 6A was removed:

http://slycontrol.ru/scr/kb/rc6.htm


My personal opinion is that, for non-technical reasons, RC-6 Mode 6A
decoding should not be included in the kernel.  That's why I didn't do
it for the HVR-1850/CX23888.

Andy
