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

Section 10

[1]

[2]

[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.
