Acknowledge Setup
This command is acknowledges to the host that a Setup packet was received. It
re-enables the Validate Buffer and Clear Buffer commands for the control IN and
control OUT endpoints. These commands are disabled automatically when a Setup
packet is received, see
Section 9.5
.
Remark:
The Acknowledge Setup command must be sent to
both
control endpoints
(IN and OUT).
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 37
.
Code (Hex): A0 to AF —
read error code (control OUT, control IN, endpoint 1 to 14)
Transaction —
read 1 byte
