6.5 STA015 CONFIGURATION FILE FORMAT
The STA015 Configuration File is an ASCII format. An example of the file format is the following:
58 1
42 4
128 15
............
It is a sequence of rows and each one can be interpreted as an I

ration file into the device, a sequence of write operation to STA015 I
The following program describes the I
