R/W

Description

SPRSi

R/(W)* Suspend/Resume Interrupt

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.

VBUSs

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

disconnected.

1: Indicates that the VBUS (USB cable) bus is

connected.

VBUSi

R/(W)* VBUS Interrupt

Set to 1 if a VBUS state changes by the USB cable

connection or disconnection. The corresponding

interrupt output is

EXIRQ0 or EXIRQ1.

Note:* The write value should always be 0 to clear this flag.

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).
