These read-only bits are serially loaded with OUT token or SETUP
token data directed at embedded device endpoint 0. The data is
received by the D0+ and D0– pins.
These write-only buffers are loaded by software with data to be sent
on the USB bus on the next IN token directed at embedded device
endpoint 0.
These write-only buffers are loaded by software with data to be sent
on the USB bus on the next IN token directed at endpoint 1 or
endpoint 2 of the embedded device. These buffers are shared by
embedded device endpoints 1 and 2 and depend on proper
configuration of the ENDADD bit.
