NOTE:
the normalized value range is determined by scaling factor.
The scaling constants RESOLUTION_FREQUENCY_HZ and
RESOLUTION_PERIOD_NS are defined and can be changed in the LIN
Stepper software header files.
The parameters configuration uses addressing of the parameters
according to
Figure C-1 . There are four data signals in the Master

The frame frmSlaveResponse provides the LIN Stepper Controller previously addressed (initiated) with
frmMasterRequest of
l_u8_rd_service = 0x80 Upload
l_u8_rd_nodeID = node ID parameter
l_u8_wr_service
Service Byte . Specifies the Master
Request Frame service. The
application uses this Command
