boundary (the lowest three bits of USB_BTABLE register are always “000”). Buffer descriptor
table entries are described in the Section “Buffer Descriptor Table”. If an endpoint is
unidirectional and it is neither an Isochronous nor a double-buffered bulk, only one packet
buffer is required (the one related to the supported transfer direction). Other table locations
related to unsupported transfer directions or unused endpoints, are available to the user.
isochronous and double-buffered bulk endpoints have special handling of packet buffers
(Refer to “Isochronous Transfers” and “Double-Buffered Endpoints” respectively). The
relationship between buffer description table entries and packet buffer areas is depicted in
Figure 41.
