Figure 9-19. USB Embedded Device Endpoint 0 Data Register
This read/write bit causes embedded device Endpoint 1 to return a
STALL handshake when polled by either an IN or OUT token by the
USB Host Controller. Reset clears this bit.
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.
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.
1 = Send STALL handshake
0 = Default
X = Indeterminate
