9.2.7
Validate Buffer command
Indicates the presence of valid data for transmission to the USB host.
Code (Hex) —
FA
Transaction —
none.
After writing data into an endpoint’s IN buffer, the microcontroller must set the Buffer
Full flag by means of the Validate Buffer command. This indicates that the data in the
buffer are valid and can be sent to the host when the next IN token is received.
Remark:
A control IN buffer cannot be validated when the Packet Overwritten bit of
the corresponding OUT buffer is set.
9.2.8
Set Endpoint Status command
Stalls or unstalls the indicated endpoint.
Code (Hex) —
40 to 4B (endpoint index 0 to 11)
Transaction —
write 1 byte.
A stalled control endpoint is automatically unstalled when it receives a SETUP token,
regardless of the content of the packet. If the endpoint should stay in its stalled state,
the microcontroller can re-stall it with the Set Endpoint Status command.
When a stalled endpoint is unstalled (either by the Set Endpoint Status command or
by receiving a SETUP token), it is also re-initialized. This flushes the buffer: in and if it
is an OUT buffer it waits for a DATA 0 PID, if it is an IN buffer it writes a DATA 0 PID.
Remark:
A Set Endpoint Status command with a STALLED bit of logic 0 will always
initialize the endpoint, even when it was not stalled.

A logic 1 indicates that the previous packet was overwritten by a Setup Packet. In
that case the buffer is not cleared.
