A DMA transfer is terminated when any of the following conditions are met:
The DMA count is complete
DMAEN = 0
The DMA controller asserts EOT.
When the DMA transfer is terminated, the buffer is also cleared (even if the data is not
completely read) and the DMA handler is disabled automatically. For the next DMA
transfer, the DMA controller as well as the DMA handler must be re-enabled.
11.3 Endpoint descriptions
11.3.1
Endpoints with programmable FIFO size
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 66
). 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 DC 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 Programmed I/O interface or via DMA.
11.3.2
Endpoint access
Table 66
lists the endpoint access modes and programmability. All endpoints support
I/O mode access. Endpoints 1 to 14 also support DMA access. DC FIFO DMA
access is selected and enabled via bits EPIDX[3:0] and DMAEN of the
DcDMAConfiguration register. A detailed description of the DC DMA operation is
given in
Section 12
.

[2]
The total amount of FIFO storage allocated to enabled endpoints must not exceed 2462 bytes.
IN: input for the USB host (ISP1161A transmits); OUT: output from the USB host (ISP1161A receives). The data flow direction is
determined by bit EPDIR in the DcEndpointConfiguration register; see
Section 13.1.1
11.3.3
Endpoint FIFO size
The size of the FIFO determines the maximum packet size that the hardware can
support for a given endpoint. Only enabled endpoints are allocated space in the
shared FIFO storage, disabled endpoints have zero bytes.
Table 67
lists the
programmable FIFO sizes.
The following bits in the DcEndpointConfiguration register (ECR) affect FIFO
allocation:
