Applications

* By the combination of SIN and DCK, DM621 could be pre-programmed to set the operating modes that involve GCK frequency division, PWM grayscale selection, inverse IOUT PWM signal, and GCK frequency selection. DM621 also provides the auto-latch function and incorporates a particular PWM method (AS-PW
