1.9.1. Programming the S5D0127X01
The previous response is easily programmed into the S5D0127X01 loading the 0, 8, 16, 24 etc. values into the
GAMMA0,1,2,3 locations. Thus every 8th value is stored. The S5D0127X01 will use linear interpolation to generate
the values between every 8th points. This is shown in the following figure.
