13.3 General commands
Table 95:
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
Code (Hex): F4 — acknowledge set-up
Transaction — none
This command returns the status of the last transaction of the selected endpoint, as
stored in the DcErrorCode register. Each new transaction overwrites the previous
status information. The bit allocation of the DcErrorCode register is shown in
Table
Code (Hex): A0 to AF — read error code (control OUT, control IN, endpoint 1 to 14)
Transaction — read 1 word

Description
This bit is set by hardware, a 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 a logic 1
the firmware must stop ongoing set-up 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).
reserved
Description
A logic 1 indicates that a new event occurred before the
previous status was read.
This bit indicates the PID type of the last successfully received
or transmitted packet (0 = DATA0 PID, 1 = DATA1 PID).
