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 4
). 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.
The ISP1181 has 16 endpoints: endpoint 0 (control IN and OUT) plus 14 configurable
endpoints, which can be individually defined as interrupt/bulk/isochronous, IN or OUT.
Each enabled endpoint has an associated FIFO, which can be accessed either via
the parallel I/O interface or via DMA.
9.1 Endpoint access
Table 4
lists the endpoint access modes and programmability. All endpoints support
I/O mode access. Endpoints 1 to 14 also support DMA access. FIFO DMA access is
selected and enabled via bits EPIDX[3:0] and DMAEN of the DMA Configuration
Register. A detailed description of the DMA operation is given in
Section 10
.

[3]
IN: input for the USB host (ISP1181 transmits); OUT: output from the USB host (ISP1181 receives).
The data flow direction is determined by bit EPDIR in the Endpoint Configuration Register.
The total amount of FIFO storage allocated to enabled endpoints must not exceed 2462 bytes.
