TWL6030 Disable USB Insert Power-on

Other Parts Discussed in Thread: TWL6030

Hello,

The TWL6030 default boot sequence turns on the device when a USB voltage source is detected. Is there a way to disable this power-on trigger? It is a factory-set PROM option?

I have USB Vcc (+5V) tied to VBUS (B1-B4) on the TWL6030 on a custom board. As soon as I plug in a USB cable, the TWL6030 starts its boot sequence. I do not want this to happen. I only want the device to boot up when I pull down PWRON.
