Is there requirement on sequence between Vin and EN? Thanks.

All key operation of device would be active after device supply reach to min input voltage and pin internal threshold. These the basic requirements for Enables pin.
There are some waveform for start up behavior on page 26 of the datasheet.
I'm Given's colleague. I'd like to update the question and add some background.
Question: In datasheet, typical application is VIN and EN setting up at the same time. However, Customer use an MCU to control the EN of this device. there is some delay between VIN and EN rise. Please help to check if this is supported by this device.
Background: There is another device in system from Infineon that has a bug. Some PWM waveform is sent out from SW pin in the scenario that EN is pulled low and VIN is set up.
Thanks for background.
It is okay to have delay between VIN and Enable pin. However, Is it possible to share the waveform shared by customer ? If it is confidential then I would like to take it offline. I would like to check the delay expected from MCU on EN pin.
I will send you mail.
