ISP1183
Low-power USB Peripheral Controller with DMA
Each programmable FIFO can independently be congured through its ECR. The total
physical size of all enabled endpoints (IN plus OUT), however, must not exceed
2462 bytes.
Table 6 shows an example of a conguration tting in the maximum available space of
2462 bytes. The total number of logical bytes in the example is 1311. The physical storage
capacity used for double buffering is managed by the device hardware and is transparent
to the user.
9.3 Endpoint initialization
In response to standard USB request Set Interface, rmware must program all 16 ECRs of
the ISP1183 in sequence (see Table 4), whether endpoints are enabled or not. The
hardware will then automatically allocate FIFO storage space.
If all endpoints have successfully been congured, rmware must return an empty packet
to the control IN endpoint to acknowledge success to the host. If there are errors in the
endpoint conguration, rmware must stall the control IN endpoint.
