13.2.7 Acknowledge SETUP (F4H)
13.3.1 Read Endpoint Error Code (R: A0H–AFH)
13.3 General commands
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 SETUP
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

no error
PID encoding error; bits 7 to 4 are not the inverse of bits 3 to 0
PID unknown; encoding is valid, but PID does not exist
unexpected packet; packet is not of the expected type (token, data, or
acknowledge), or is a SETUP token to a non-control endpoint

Description
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).
