1.9.1. Programming the S5D2650
The previous response is easily programmed into the S5D2650 loading the 0, 8, 16, 24 etc. values into the
GAMMA0,1,2,3 locations. Thus every 8th value is stored. The S5D2650 will use linear interpolation to generate the
values between every 8th points. This is shown in the following figure.
