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.
