PAD State
Figure 30-9
• In the Idle state, the pad is put in low power consumption mode.
• In the Active state, the pad is working.
Figure 30-10
The Suspend interrupt flag (SUSP) is set and the Wake-Up interrupt flag (WAKEUP) 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 set. It
returns to the Active state when USBE = 1 and DETACH = 0.
