USUSPEND USBPWR

Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

bit 31-8 Unimplemented: Read as ‘0’

bit 7 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

bit 6-5 Unimplemented: Read as ‘0’

bit 4 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

bit 3 USBBUSY: USB Module Busy bit(1)

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

Note: When USBPWR = 0 and USBBUSY = 1, status from all other registers is invalid and writes to all

USB module registers produce undefined results.

bit 2 Unimplemented: Read as ‘0’

bit 1 USUSPEND: USB Suspend Mode bit

1 = USB module is placed in Suspend mode

(The 48 MHz USB clock will be gated off. The transceiver is placed in a low-power state.)

0 = USB module operates normally

bit 0 USBPWR: USB Operation Enable bit

1 = USB module is turned on

0 = USB module is disabled

(Outputs held inactive, device pins not used by USB, analog features are shut down to reduce power

consumption.)
