14.3.19 USB Interrupt Enable Register 0 (UIER0)
UIER0 enables the interrupt request indicated in the interrupt flag register 0 (UIFR0). When an
interrupt flag is set while the corresponding bit in UIER0 is set to 1, an interrupt is requested by
asserting the corresponding EXIRQ0 or EXIRQ1. Either EXIRQ0 or EXIRQ1 must be selected by
the interrupt select register 0 (UISR0).

Description
Set to 1 if a transition from normal state to suspend
state or suspend state to normal state has occurred.
The corresponding interrupt output is IRQ6. This bit
can be used to cancel power-down mode at resuming.
VBUS Status
VBUSs is a status bit to indicate the VBUS state by
the USB cable connection or disconnection. However,
an interrupt cannot be requested by VBUSs.
0: Indicates that the VBUS (USB cable) bus is
1: Indicates that the VBUS (USB cable) bus is
Set to 1 if a VBUS state changes by the USB cable
connection or disconnection. The corresponding
interrupt output is EXIRQ0 or EXIRQ1.
Description
Enables the BRST interrupt.
