Description

PWR USB supply control register

Fields

USB33DEN

V DDUSB voltage level detector enable

0 (B_0x0): V DDUSB voltage level detector disabled

1 (B_0x1): V DDUSB voltage level detector enabled

USB33SV

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

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

1 (B_0x1): V DDUSB is valid.
