Regarding the TUSB4041, when VDD11 is started before VDD33, a voltage of about 0.6V is generated at the VDD33 pin. Is there a way around this? This effect prevents the PMIC that generates 3.3V from booting.

Hello:
VDD33 should power on before 1.1v, can you send waveform picture together with GRST?
