Table 66. Device n Endpoint n Status Register
Register Description
The Device n Endpoint n Status register provides packet status
information for the last transaction received or transmitted. This
register is updated in hardware and does not need to be cleared
by firmware. There are a total of eight endpoints for each of the
two ports. All endpoints have the same definition for their Device
n Endpoint n Status register.
The Device n Endpoint n Status register is a memory based
register that must be initialized to 0x0000 before USB Device
operations are initiated. After initialization, do not write to this
register again.
Overflow Flag (Bit 11)
The Overflow Flag bit indicates that the received data in the last
data transaction exceeded the maximum length specified in the
Device n Endpoint n Count register. The Overflow Flag must be
checked in response to a Length Exception signified by the
Length Exception Flag set to ‘1’.
1: Overflow condition occurred
0: Overflow condition did not occur
Underflow Flag (Bit 10)
The Underflow Flag bit indicates that the received data in the last
data transaction was less then the maximum length specified in
the Device n Endpoint n Count register. The Underflow Flag must
be checked in response to a Length Exception signified by the
Length Exception Flag set to ‘1’.
1: Underflow condition occurred
0: Underflow condition did not occur

OUT Exception Flag (Bit 9)
The OUT Exception Flag bit indicates when the device received
an OUT packet when armed for an IN.
1: Received OUT when armed for IN
0: Received IN when armed for IN
IN Exception Flag (Bit 8)
The IN Exception Flag bit indicates when the device received an
IN packet when armed for an OUT.
1: Received IN when armed for OUT
0: Received OUT when armed for OUT
Stall Flag (Bit 7)
The Stall Flag bit indicates that a Stall packet was sent to the
host.
1: Stall packet was sent to the host
0: Stall packet was not sent
NAK Flag (Bit 6)
The NAK Flag bit indicates that a NAK packet was sent to the
host.
1: NAK packet was sent to the host
0: NAK packet was not sent
Length Exception Flag (Bit 5)
The Length Exception Flag bit indicates the received data in the
data stage of the last transaction does not equal the maximum
Endpoint Count specified in the Device n Endpoint n Count
register. A Length Exception can either mean an overflow or
