FUNCTIONAL DEVICE OPERATION

LOGIC COMMANDS AND REGISTERS

LOGIC COMMANDS AND REGISTERS

All registers and POWER ON/OFF channels should be reconfigured every time the part gets recovered from a POR or shutdown

condition.

The configuration sequence every time the part is power up should be as follows:

1. Take the PWM pin low

2. Power up the part

3. Configure all registers

4. Take the PWM pin High

For configuring the part once in operation it is recommended to follow this sequence:

1. Take the PWM pin low

2. Configure the registers

3. Take the PWM pin High

Special considerations should be taken for re-configuring POWER ON/OFF functions, please refer to the POWER OFF and POWER

ON LED CHANNELS section.
