13.2.5
Clear Endpoint Buffer (70H, 72H–7FH)
This command unlocks and clears the buffer of the selected OUT endpoint, allowing
the reception of new packets. Reception of a complete packet causes the Buffer Full
flag of an OUT endpoint to be set. Any subsequent packets are refused by returning a
NAK condition, until the buffer is unlocked using this command. For a double-buffered
endpoint this command switches the current FIFO for CPU access.
Remark:
For special aspects of the control OUT endpoint see
Section 11.3.6
.
Code (Hex): 70, 72 to 7F —
clear endpoint buffer (control OUT, endpoint 1 to 14)
Transaction —
none
13.2.6
DcEndpointStatusImage register (D0H–DFH)
This command is used to check the status of the selected endpoint FIFO without
clearing any status or interrupt bits. The command accesses the
DcEndpointStatusImage register, which contains a copy of the DcEndpointStatus
register. The bit allocation of the DcEndpointStatusImage register is shown in
Table 94
.
Code (Hex): D0 to DF —
check status (control OUT, control IN, endpoint 1 to 14)
Transaction —
write/read 1 word

Description
EPSTAL
This bit indicates whether the endpoint is stalled or not
(1 = stalled, 0 = not stalled).
EPFULL1
Logic 1 indicates that the secondary endpoint buffer is full.
EPFULL0
Logic 1 indicates that the primary endpoint buffer is full.
DATA_PID
This bit indicates the data PID of the next packet (0 = DATA PID,
1 = DATA1 PID).
OVERWRITE
This bit is set by hardware, logic 1 indicating that a new Setup
packet has overwritten the previous set-up information, before it
was acknowledged or before the endpoint was stalled. If writing
the set-up data has finished, this bit is cleared by a read action.
Firmware must check this bit before sending an Acknowledge
Setup command or stalling the endpoint. Upon reading logic 1
the firmware must stop ongoing set-up actions and wait for a
new Setup packet.
SETUPT
Logic 1 indicates that the buffer contains a Setup packet.
CPUBUF
This bit indicates which buffer is currently selected for CPU
access (0 = primary buffer, 1 = secondary buffer).
