Endpoint descriptions
Each USB device is logically composed of several independent endpoints. An
endpoint acts as a terminus of a communication flow between the host and the
device. At design time each endpoint is assigned a unique number (endpoint
identifier, see
Table 3
). The combination of the device address (given by the host
during enumeration), the endpoint number and the transfer direction allows each
endpoint to be uniquely referenced.
7.1 Endpoint configuration
The ISP1130 hub has 1 to 2 downstream ports and 1 to 3 embedded functions. The
upstream and downstream ports are fully handled by hardware and require no
firmware intervention. Downstream port 2 can be disabled by connecting both D
+
and
D
to V
CC
.
The number of embedded functions can be configured from 1 to 3 via the USBCONA
register. These embedded functions give access to the keyboard controller and other
optional software functions. The functions are assigned as follows:
Embedded function 1: standard keyboard
Embedded function 2:
multimedia functions (e.g. volume control)
ACPI system control
application launch keys
Embedded function 3: user-defined functions.
Each embedded function has two endpoint types: endpoint 0 (control) and endpoint 1
(generic: bulk and/or interrupt). The embedded function endpoints can handle a
maximum of 8 bytes per transfer.
