Power Management
To save power, you can disable the Chips 65545 by setting the JP1
jumper to 1 (closed). This clears the memory and interrupts input and
output. You can use the included software if you only want to stop
output. To disable the flat panel's backlight, set CN2-pin40 (EN-
ABKL) to 0 (open).
