States identified by an asterisk (*)

• Idle (standby/suspend) state: Either one of the following 4 states:

- Either one of AVDDPHY1 and AVDDPHY2 is lower than the guaranteed operating voltage.

- (USB register) DeviceControl: SuspendSts=Susp3endSet=1 (USBPHY suspended state)

- (USB register) DeviceControl: RstPhy=1 (USBPHY reset state)

- (SYSCON register) USBCTL: SHSTBY=1 (USBPHY standby state)

For details on the registers, see the LC823410-09C-E User’s Manual (Expansion Module).

• Active-state: Any state in which the IC is not in any of the Idle (standby/suspend) states.
