TPS929121-Q1: LEDs glow although PWM registers are zero

Part Number: TPS929121-Q1

Hello,

 i want control TPS929121 only with PWM registers. I set all PWML and PWM registers to zero, but LEDs are still glowing.

Only with setting CONF_ENx registers to zero, the LEDs are not active. But i want to reduce bus load and software calculation and not also send this commands to disable LEDs.

If it is important i also use exponential curve (CONF_EXPEN).
