Peter,
Read it, scanned it several times each day, particularly when writing a response. Printed two copies, one next to the lathe, one on my desk, both annotated and pages tabbed etc.
BUT will continue to reread.
Found the detail of Pins 1 &2 in the release notes posted on the Yahoo group, but not as yet found direct or specific mention of what the other settings of the HEX switch do.
Guess I could set the switch, see if it still communicates and if it does read the config registers and overlay the bitcode to the function. Then there would be an easy table of each valid HEX switch setting and what it enabled/disabled. BUT as yet not found this level of information in the manual, like you say will reread.
Peter
