User manual
9.11.13 Clear Buffer (Command: 0xF2, Data: read 1 byte (optional))
Table 177. Set Endpoint Status command description
When an OUT packet sent by the host has been received successfully, an internal
hardware FIFO status Buffer_Full flag is set. All subsequent packets will be refused by
returning a NAK. When the device software has read the data, it should free the buffer by
issuing the Clear Buffer command. This clears the internal Buffer_Full flag. When the
buffer is cleared, new packets will be accepted.
When bit 0 of the optional data byte is 1, the previously received packet was over-written
by a SETUP packet. The Packet over-written bit is used only in control transfers.
According to the USB specification, a SETUP packet should be accepted irrespective of
the buffer status. The software should always check the status of the PO bit after reading
the SETUP data. If it is set then it should discard the previously read data, clear the PO bit
by issuing a Select Endpoint/Clear Interrupt command, read the new SETUP data and
again check the status of the PO bit.

Description
Stalled endpoint bit. 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 CPU can stall it again by setting this bit. 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 case of an OUT buffer it waits for a
DATA 0 PID; in case of an IN buffer it writes a DATA 0 PID. There
is no change of the interrupt status of the endpoint. When
already unstalled, writing a zero to this bit initializes the endpoint.
When an endpoint is stalled by the Set Endpoint Status
command, it is also re-initialized.
The endpoint is unstalled.
The endpoint is stalled.
Reserved, user software should not write ones to reserved bits.
The value read from a reserved bit is not defined.
Disabled endpoint bit.
The endpoint is enabled.
The endpoint is disabled.
Rate Feedback Mode.
Interrupt endpoint is in the Toggle mode.
Interrupt endpoint is in the Rate Feedback mode. This means
that transfer takes place without data toggle bit.
Conditional Stall bit.
Unstalls both control endpoints.
Stall both control endpoints, unless the STP bit is set in the
Select Endpoint register. It is defined only for control OUT
endpoints.
