13.2 SCENARIO 2: AUTOMATIC POINT-TO-POINT
CONNECTION
LMX9820 at both sides.
Example:
Serial Cable Replacement.
Device #1 controls the link setup with a few commands as
described.
If step 5 is executed, the stored default device is connected
(step 4) after reset (in Automatic mode only) or by sending
the command “Connect to Default Device”. The command
can be sent to the device at any time.
If step 6 is left out, the microcontroller has to use the com-
mand “Send Data” instead of sending data directly to the
module.
