Code (Hex): 70, 72 to 7F — clear endpoint buffer (control OUT, endpoints 1 to 14)
Transaction — none (code only)
This command is used to check the status of the selected endpoint buffer memory, 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
Code (Hex): D0 to DF — check status (control OUT, control IN, endpoints 1 to 14)
Transaction — write or read 1 byte (code or data)
Table 128. DcEndpointStatusImage register: bit description
This command acknowledges to the host that a set-up packet is received. The arrival of a
set-up packet disables the Validate Buffer and Clear Buffer commands for the control IN
and OUT endpoints. The microprocessor must re-enable these commands by sending an
acknowledge set-up command, see
Code (Hex): F4 — acknowledge set up
Transaction — none (code only)

Description
This bit indicates whether the endpoint is stalled or not (1 = stalled; 0 =
not stalled).
Logic 1 indicates that the secondary endpoint buffer is full.
Logic 1 indicates that the primary endpoint buffer is full.
This bit indicates data PID of the next packet (0 = DATA0 PID; 1 =
DATA1 PID).
This bit is set by hardware. Logic 1 indicates that a new set-up packet
has overwritten the previous set-up information, before it was
acknowledged or before the endpoint was stalled. Once writing of the
set-up data is completed, a read back of this register clears this bit.
Firmware must check this bit before sending an acknowledge set-up
command or stalling the endpoint. On reading logic 1, firmware must
stop ongoing set-up actions and wait for a new set-up packet.
Logic 1 indicates that the buffer contains a set-up packet.
This bit indicates which buffer is currently selected for CPU access (0 =
primary buffer; 1 = secondary buffer).
