Nonvolatile RAM ('N')
Function: Saves/restores controller settings in the on-board nonvolatile
memory (NVRAM). NVRAM can be used to store power-on defaults.
Power-on defaults are from NVRAM if the J7 jumper is installed. The use of
NVRAM is discussed on page 8 and in Chapter 4—SmartSet Tutorial.
The least significant bit of the Direction byte is 1 to save the settings in NVRAM,
or 0 to restore the settings from NVRAM.
The Areas byte has the following bit positions:
Bit Area
0 Setup Area
1 Calibration
2 Scaling
The Setup Area consists of all parameters except the Calibration and Scaling
parameters. All three areas may be saved or restored in any combination by setting
the appropriate bits.
The least significant bit of the Page byte is 0 for the primary area, or 1 for the
secondary area. The Page is only required if setting the Calibration or Scaling
parameters, as the controller only has one Setup Area.
Factory default settings in NVRAM are given in each command description.
