When the USB module receives a USB token on an enabled endpoint, it interrogates the BDT. The USB
module reads the corresponding endpoint BD entry and determines if it owns the BD and corresponding
data buffer.
17.4.2.3
The buffer descriptors (BDs) are groups of registers that provide endpoint buffer control information for
the USB module and the MCU. The BDs have different meanings based on who is reading the BD in
memory.
The USB module uses the data stored in the BDs to determine:
The microcontroller uses the data stored in the BDs to determine:
