To get the design parameters in Section 8.2.2, the following program steps can be referred.

After VCC powering up and wait around 1ms,

1. Set INSTABLINK_DIS = 1 to disable instant blinking (Write 02h to register 00h)
2. Set CHIP_EN = 1 to enable the device (Write 03h to register 00h)
3. Set MAX_CURRENT = 1h to set 51mA maximum output LED current (Write 01h to register 01h)
4. Set 51mA maximum current for red LEDs, 40.8mA maximum current for green, blue and white LEDs (Write FFh to registers 14h, write CCh to registers 15h, 16h and 17h)
5. Enable all 4 LEDs (Write 0Fh to register 02h)
6. Set red LED in manual mode, set green, blue and white LEDs in autonomous animation mode, and enable blue LED exponential PWM dimming (Write 4Eh to register 04h)
7. Select ENGINE0 for green LED, ENGINE1 for blue LED and ENGINE2 for white LED (Write 90h to register 05h)
8. Send UPDATE_CMD to make above step2, step4, step5 and step6 configurations take effect (Write 55h to register 0Fh)
9. Set red LED PWM duty cycle as 50% (Write 80h to register 18h)

   After this step, the read LED is turned on.

10. Check ENGINE_BUSY flag by reading the FLAG register (Read register 40h)
    • If ENGINE_BUSY = 1, send STOP_CMD to clear ENGINE_BUSY flag as showed in the Internal Engine Busy Status (Write AAh to register 11h), then move to next step.
    • If ENGINE_BUSY = 0, move to next step directly.
11. Select PATTERN0 for ENGINE0_ORDER0, PATTERN1 for ENGINE1_ORDER0 and PATTERN2 for ENGINE2_ORDER0 (Write 00h to register 06h, write 01h to register 07h, write 02h to register 08h)
12. Enable ENGINE0_ORDER0, ENGINE1_ORDER0 and ENGINE2_ORDER0 (Write 11h to register 0Ah, write 01h to register 0Bh)
13. Set PATTERN0 parameters as showed in Table 8-2 to realize 5Hz blinking effect on green LED, set PATTERN1 parameters as showed in Table 8-3 to realize breathing effect on blue LED and set PATTERN2 parameters as showed in Table 8-4 to realize 1Hz blinking effect on white LED.
14. Send START_CMD to initiate the animation (Write FFh to register 10h)

After this step, the red LED keeps constant ON, the green LED keeps blinking with 5Hz frequency and blue LED keeps breathing in 2.4s period and white LED keeps blinking with 1Hz frequency.
