MOTOROLA
USB Device Port
•
USBD_SUSPND
—Transceiver Suspend Enable. This signal, when high, activates a low-power
state in the USB transceiver. Normally, when suspended, the transceiver drives USBD_RCV low
and tri-state the USB bus signals D+ and D-.
•
USBD_RCV
—USB Module Receive Data. This signal is a CMOS level driven signal provided by
the external USB transceiver. The signal is derived from the D+ and D- differential input to the
transceiver.
•
USBD_VP
—Input D+ signal connected directly to the D+.
•
USBD_VM
—Input D- signal connected directly to the D-.
28.2.7 Pin Configuration for USB
Table 28-2 lists the pins used by the USB module. These pins are multiplexed with other functions on the
device and must be configured for USB operation.
NOTE:
The user must ensure that the data direction bits in the GPIO are set to the
correct direction for proper operation. See Section 32.5.1, “Data Direction
Registers,” on page 32-9 for details.
