8.121. PRESETP -- Set Which Preset Will Be Activated At Power-
Up
This command sets or queries the power-up preset, which is executed each time the device powers up. The
power-up preset must be one of the factory presets (0-15) or one of the user presets (16-47).
This command is saved to global non-volatile memory and is not part of a preset. Its value is saved each time it
is changed. It will retain its value after power-down. Since this command writes to non-volatile memory, there
will be a delay before an acknowledgment is returned.
