UACTPND: USB Activity Pending bit
1 = USB bus activity has been detected; but an interrupt is pending, it has not been generated yet
0 = An interrupt is not pending
Unimplemented: Read as ‘0’
USLPGRD: USB Sleep Entry Guard bit
1 = Sleep entry is blocked if USB bus activity is detected or if a notification is pending
0 = USB module does not block Sleep entry
USBBUSY: USB Module Busy bit
1 = USB module is active or disabled, but not ready to be enabled
0 = USB module is not active and is ready to be enabled
Unimplemented: Read as ‘0’
USUSPEND: USB Suspend Mode bit
1 = USB module is placed in Suspend mode
0 = USB module operates normally
USBPWR: USB Operation Enable bit
1 = USB module is turned on
0 = USB module is disabled

(The 48 MHz USB clock will be gated off. The transceiver is placed in a low-power state.)
(Outputs held inactive, device pins not used by USB, analog features are shut down to reduce power
consumption.)
When USBPWR = 0 and USBBUSY = 1, status from all other registers is invalid and writes to all
USB module registers produce undefined results.
