USB interface
USB Host The USB Host consists of a USB Host controller that conforms to the Open Host
Controller Interface (OHCI) specification and a wrapper to interface the module to
the rest of the system. The USB Host interfaces to the internal USB PHY provided by
the NS9360, and is connected to an optional hub on the module.)
USB Device The USB Device module provides a USB 2.0-compliant interface for both full-speed
(12Mbps) and low-speed (1.5 Mbps) operation. The module supports one
bidirectional endpoint and up to 10 unidirectional endpoints that can be individually
programmed for endpoint type (interrupt, bulk, or isochronous) and direction. Each
endpoint is assigned to a DMA channel in a multi-channel BBus DMA controller. The
USB Device module interfaces to either the internal NS9360 USB PHY or an external
USB PHY using GPIO.
Support Both USB Host and Device can be supported at the same time:
USB Device, in this case, must use the only the signals shown in the table in the
section "USB Device only," beginning on page 69.
USB Host can be on the module or external to the module. If USB Host is
external to the module, use only the signals shown in the table in the section
"No USB on module," beginning on page 68.
Note:
All output drivers for USB meet the standard USB driver specifications.
USB Host with
hub on module
Connect up to two ports using the dual USB connector, P6.
All hub signals out to the SO-DIMM edge connector, P3, are reserved for future
use.
No USB on
module
USB data lines are brought out on DM1 and DP1.
Terminate DM1 and DP1 with 15K pulldowns, if not used.
OVR1# and PON1# are multiplexed with GPIO16 and GPIO17.
