20.4.5 Fixed endpoint configuration
Table 295. USB related acronyms
The USB OTG controller contains a Tx buffer to store data to be transmitted on the USB
and an Rx buffer to store data received from the USB. The Rx buffer contains 256 words,
and the Tx buffer contains 128 words for each endpoint in device mode and 512 words in
host mode.
