Table 8. PWM Application Scenarios

APPLICATION RECOMMENDED CONFIGURATION

All outputs static without PWM

Set the master and global intensity register 0x0E to any value from 0x00 to 0x0F.

The global intensity G bit in the configuration register is don't care.

The output intensity registers 0x10 through 0x17 are don't care.

A mix of static and PWM outputs, with PWM

outputs using different PWM settings

Set the master and global intensity register 0x0E to any value from 0x10 to 0xFF.

Clear global intensity G bit to zero in the configuration register to disable global

intensity control.

For the static outputs, set the output intensity value to 0xF.

For the PWM outputs, set the output intensity value in the range 0x0 to 0xE.

A mix of static and PWM outputs, with PWM

outputs all using the same PWM setting

As above. Global intensity control cannot be used with a mix of static and PWM

outputs, so write the individual intensity registers with the same PWM value.

All outputs PWM using the same PWM

setting

Set the master and global intensity register 0x0E to any value from 0x10 to 0xFF.

Set global intensity G bit to 1 in the configuration register to enable global intensity

control.

The master and global intensity register 0x0E is the only intensity register used.

The output intensity registers 0x10 through 0x17 are don't care.
