Figure 26-9. Pad Events
The SUSP bit is set and the Wake-Up Interrupt (WAKEUP) bit in UDINT is cleared when a USB
“Suspend” state has been detected on the USB bus. This event automatically puts the USB pad
in the Idle state. The detection of a non-idle event sets WAKEUP, clears SUSP and wakes up
the USB pad.
Moreover, the pad goes to the Idle state if the macro is disabled or if the DETACH bit is written to
one. It returns to the Active state when USBE is written to one and DETACH is written to zero.
• In the Idle state, the pad is put in low power consumption mode, i.e., the differential receiver
• In the Active state, the pad is working.

avoid floating lines.
