9.5.8 USB Embedded Device Endpoint 0 Data Registers (DE0D0-DE0D7)
DE0Rx7-DE0Rx0 — Embedded Device Endpoint 0 Receive Data Buffer
These read only bits are serially loaded with OUT token or SETUP token data directed at embedded
device Endpoint 0. The data is received over the USB’s D0+ and D0– pins.
DE0Tx7-DE0Tx0 — Embedded Device 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 embedded device Endpoint 0.
9.5.9 USB Embedded Device Endpoint 1/2 Data Registers (DE1D0-DE1D7)
DE1TD7-DE1TD0 — Embedded Device Endpoint 1/ Endpoint 2 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 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.
