Endpoint Packet Status [Address a = (EP# * 10h)+3, b = (EP# * 10h)+Bh]. The packet status contains information relative to
the packet that is received or transmitted. The register is defined as follows:
Endpoint Transfer Count [Address a = (EP# * 10h)+4, b =
(EP# * 10h)+Ch]. As a peripheral device, the Endpoint
Transfer Count register is only important with OUT tokens
(host sending the slave data). When a host sends the
peripheral data, the Transfer Count register contains the
difference between the Endpoint Base Length and the actual
number of bytes received in the last packet. In other words, if
the Endpoint Base Length register was set for 64 (40h) bytes
and an OUT token was sent to the endpoint that only had 16
(10h) bytes, the Endpoint Transfer Count register has a value
of 48 (30h). If more bytes were sent in an OUT token then the
Endpoint Base Length register was programmed for, the
overflow flag is set in the Endpoint Packet Status register and
is considered a serious error.
USB Control Registers
The USB Control registers manage communication and data
flow on the USB. Each USB device is composed of a collection
of independently operating endpoints. Each endpoint has a
unique identifier, which is the Endpoint Number. For more
details about USB endpoints, refer to the USB Specification
1.1, Section 5.3.1.
The Control and Status registers are mapped as follows:

Overflow
Overflow condition - maximum length exceeded during receives. This is considered a
serious error. The maximum number of bytes that can be received by an endpoint is deter-
mined by the Endpoint Base Length register for each endpoint. The Overflow bit is only
relevant during OUT Tokens from the host.
4
Setup
'1' indicates Setup Packet. If this bit is set, the last packet received was a setup packet.
3
Sequence
This bit indicates if the last packet was a DATA0 (0) or DATA1 (1).
2
Time-out
This bit is not used in slave mode.
1
Error
Error detected in transmission, this includes CRC5/16 and PID errors.
0
ACK
Transmission Acknowledge.
