14.2.7
Acknowledge Setup
This command acknowledges to the host that a SETUP packet was received. The
arrival of a SETUP packet disables the Validate Buffer and Clear Buffer commands
for the control IN and OUT endpoints. The microprocessor needs to re-enable these
commands by sending an Acknowledge Setup command, see
Section 11.3.6
.
Remark:
The Acknowledge Setup command must be sent to
both
control endpoints
(IN and OUT).
Code (Hex): F4 —
acknowledge setup
Transaction —
none
14.3 General commands
14.3.1
Read Endpoint Error Code
This command returns the status of the last transaction of the selected endpoint, as
stored in the Error Code Register. Each new transaction overwrites the previous
status information. The bit allocation of the Error Code Register is shown in
Table 95
.
Code (Hex): A0 to AF —
read error code (control OUT, control IN, endpoint 1 to 14)

Description
7
EPSTAL
This bit indicates whether the endpoint is stalled or not
(1 = stalled, 0 = not stalled).
6
EPFULL1
A logic 1 indicates that the secondary endpoint buffer is full.
5
EPFULL0
A logic 1 indicates that the primary endpoint buffer is full.
4
DATA_PID
This bit indicates the data PID of the present packet (0 = DATA
PID, 1 = DATA1 PID).
3
OVERWRITE
This bit is set by hardware, a logic 1 indicating that a new Setup
packet has overwritten the previous setup information, before it
was acknowledged or before the endpoint was stalled. This bit is
cleared by reading, if writing the setup data has finished.
Firmware must check this bit before sending an Acknowledge
Setup command or stalling the endpoint. Upon reading a logic 1
the firmware must stop ongoing setup actions and wait for a new
Setup packet.
2
SETUPT
A logic 1 indicates that the buffer contains a Setup packet.
1
CPUBUF
This bit indicates which buffer is currently selected for CPU
access (0 = primary buffer, 1 = secondary buffer).
