8.133. 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.

Example
