Product data sheet
The following bits of the DcEndpointConfiguration register (ECR) affect the buffer memory
allocation:
Remark: A register change that affects the allocation of the shared buffer memory storage
among endpoints must not be made while valid data is present in any buffer memory of
the enabled endpoints. Such changes render all buffer memory contents undefined.
Table 16.
Each programmable buffer memory can independently be configured by using its ECR,
but the total physical size of all enabled endpoints (IN plus OUT) must not exceed
2462 bytes.
Table 17
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.
