12.2.7
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 microcontroller needs to re-enable these
commands by sending an Acknowledge Setup command, see
Section 9.5
.
Code (Hex): F4 —
acknowledge setup
Transaction —
none
12.3 General commands
12.3.1
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 35
.
Code (Hex): A0 to AF —
read error code (control OUT, control IN, endpoint 1 to 14)
Transaction —
read 1 byte
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.
A logic 1 indicates that the buffer contains a Setup packet.
This bit indicates which buffer is currently selected for CPU
access (0 = primary buffer, 1 = secondary buffer).

UNREAD
A logic 1 indicates that a new event occurred before the
previous status was read.
DATA01
This bit indicates the PID type of the last successfully received
or transmitted packet (0 = DATA0 PID, 1 = DATA1 PID).
