Description

PWR USB supply control register

Fields

USB33DEN

Vsub DDUSB/sub voltage level detector enable

0 (B_0x0): Vsub DDUSB/sub voltage level detector disabled

1 (B_0x1): Vsub DDUSB/sub voltage level detector enabled
USB33SV

independent USB supply valid This bit is used to validate the Vsub DDUSB/sub supply for electrical and logical isolation purpose. Setting this bit is mandatory to use the USBFS peripheral. If Vsub DDUSB/sub is not always present in the application, the Vsub DDUSB/sub voltage monitor can be used to determine whether this supply is ready or not.

0 (B_0x0): Vsub DDUSB/sub is not present. Logical and electrical isolation is applied to ignore this supply.

1 (B_0x1): Vsub DDUSB/sub is valid.
