underflow and the Overflow and Underflow flags (bits 11 and 10
respectively) must be checked to determine which event
occurred.
1: An overflow or underflow condition occurred
0: An overflow or underflow condition did not occur
Setup Flag (Bit 4)
The Setup Flag bit indicates that a setup packet was received.
In device mode setup packets are stored at memory location
0x0300 for Device 1 and 0x0308 for Device 2. Setup packets are
always accepted regardless of the Direction Select and Arm
Enable bit settings as long as the Device n EP n Control register
Enable bit is set.
1: Setup packet was received
0: Setup packet was not received
Sequence Flag (Bit 3)
The Sequence Flag bit indicates whether the last data toggle
received was a DATA1 or a DATA0. This bit has no effect on
receiving data packets; sequence checking must be handled in
firmware.
1: DATA1 was received
0: DATA0 was received

Table 67. Device n Endpoint n Count Result Register
Register Description
The Device n Endpoint n Count Result register contains the size
difference in bytes between the Endpoint Count specified in the
Device n Endpoint n Count register and the last packet received.
If an overflow or underflow condition occurs, that is, the received
packet length differs from the value specified in the Device n

Timeout Flag (Bit 2)
The Timeout Flag bit indicates whether a timeout condition
occurred on the last transaction. On the device side, a timeout
can occur if the device sends a data packet in response to an IN
request but then does not receive a handshake packet in a
predetermined time. It can also occur if the device does not
receive the data stage of an OUT transfer in time.
1: Timeout occurred
0: Timeout condition did not occur
Error Flag (Bit 2)
The Error Flag bit is set if a CRC5 and CRC16 error occurs, or if
an incorrect packet type is received. Overflow and underflow are
not considered errors and do not affect this bit.
1: Error occurred
0: Error did not occur
ACK Flag (Bit 0)
The ACK Flag bit indicates whether the last transaction was
ACKed.
1: ACK occurred
0: ACK did not occur
Endpoint n Count register, the Length Exception Flag bit in the
Device n Endpoint n Status register is set. The value in this
register is only valued when the Length Exception Flag bit is set
and the Error Flag bit is not set; both bits are in the Device n
Endpoint n Status register.
