After VCC powering up, the instant blinking is disabled by setting INSTABLINK_DIS = 1 through I²C command, then enable the device by setting CHIP_EN = 1. Set the maximum current for each output. Then set the device configuration registers to enable the output, select the dimming control mode for each output, and select the animation engine for the output in autonomous animation mode. Finally, Send UPDATE_CMD to make the prior configuration settings take effect.

For the output channel that is configured in manual mode, the output PWM changes immediately when the corresponding manual PWM register value is set.

For the output channel that is configured in autonomous animation mode, firstly, select animation engine for output. Secondly, construct the animation engine by setting the engine configure registers to select the animation pattern to map to the engine order and enable or disable the engine order. Then, build the animation patterns as required by setting pattern unit parameters. Finally, send START_CMD to initiate the autonomous animation.

The detailed program procedure is illustrated in Figure 8-2.
