Figure 9-26. USB Endpoint 0 Data Registers (UE0D0–UE0D7)
UE0Rx7–UE0Rx0 — Endpoint 0 Receive Data Buffer
These read-only bits are serially loaded with OUT token or SETUP
token data directed at endpoint 0. The data is received over the USB’s
D+ and D– pins.
UE0Tx7–UE0Tx0 — Endpoint 0 Transmit Data Buffer
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 0.
