Hi,

Is there any trick to change the resolution and leave the TH TL registers unchanged?

Or the only possible way of doing that is:

  1. Read "Scratchpad [BEh]" and store the TH and TL in appropriate variables.

  2. Use the "Write Scratchpad [4Eh]" command and use the previously saved TH and TL bytes along with the resolution byte I want.

Thanks

Guess not!

AFAIK, the only way is as you described.
