PowerLevel: (0) At this time low speed is not supported. The resulting heating and cooling of the processor causes analog
calibration problems. Intended operation: Specifies different system clock speeds for the Control processor. Streaming
does not work at fixed low speed. The WriteMask behaves differently for this parameter. The value passed for PowerLevel
always becomes the current operating condition. If the WriteMask bit 0 is set, the value passed becomes the current value
and the default value, meaning it is written to flash and used at reset. The return value of this parameter is a read of the
power-up default.
FIO/EIO/CIO/MIO: (0) If the WriteMask bit 1 is set, the values passed become the default values, meaning they are written to
flash and used at reset. Regardless of the mask bit, this function has no effect on the current settings. These defaults are only
used if bit 8 of MIODirState is clear. The return value of this parameter is a read of the power-up defaults.
DAC#: (0) If the WriteMask bit 2 is set, the values passed become the default values, meaning they are written to flash and
used at reset. Regardless of the mask bit, this function has no effect on the current settings. The return value of this
parameter is a read of the power-up defaults.
ControlFWVersion: Fixed parameter specifies the version number of the Control firmware. A firmware upgrade will
generally cause this parameter to change.
