97 kHz individual brightness control signal. GRPFREQ is group frequency for
global blinking control when DMBLNK bit (MODE2 register, Group control =
blinking) is programmed with logic 1.
– ‘LEDOUT’ LED driver output state for LED0 to LED15 as shown in Figure 9 .
4. Click the ‘LEDOUT’ configuration screen and select ‘PWMn & GRPPWM’ for LED[1:3]
(see Figure 9 ).
5. Click the ‘PWM 0 to 7’ configuration screen and move the PWM1 (red),
PWM2 (green), PMW3 (blue) bars for color mixing (see Figure 6 ).
6. Once you set a color on D3 RGB LED with the PWM[1:3] values, click the ‘Group
control’ configuration screen and move the GRPPWM bar for dimming effect (see
Figure 8 ).
