This is much simpler than you seem to think.

Nope, there's no need to wait for anything.

1. If you get an LSB, change it immediately.

2. If you get an MSB, change it immediately _and_ together with that change 
the LSB so that the distance between the old and the new value is minimized 
(i.e. depending on direction and perhaps signedness of the value you either 
set the LSB to 0x7f or 0x00).

You always need to send the MSB first, if any.
