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.
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.
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.
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.
