Product data
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 renders all buffer memory contents
undefined.
Table 15:
Each programmable buffer memory can be independently configured by using its
ECR, but the total physical size of all enabled endpoints (IN plus OUT) must not
exceed 2462 bytes.
Table 16
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.
