Setup Packet
A ‘1’ indicates the last received packet had a
SETUP token.
STALL
A ‘1’ indicates the endpoint is stalled.
Data 0/1 Packet
A ‘1’ indicates if the last received or sent
packet had a DATA1 PID.
Buffer Full
A ‘1’ indicates that the buffer is full.
Read Buffer
Command
Data
: F0h
: Read multiple bytes (max 10)
The Read Buffer command is followed by a number of data reads,
which return the contents of the selected endpoint data buffer. After
each read, the internal buffer pointer is incremented by 1.
The buffer pointer is not reset to the buffer start by the Read Buffer
command. This means that reading or writing a buffer can be
interrupted by any other command (except for Select Endpoint), or
can be done by more than one I
2
C transaction (read the first 2 bytes
to get the number of data bytes, then read the rest in other
transactions).
The data in the buffer are organized as follows:
byte 0:
Reserved: can have any value
byte 1:
Number/length of data bytes
byte 2:
Data byte 1
byte 3:
Data byte 2
Write Buffer
Command
Data
: F0h
: Write multiple bytes (max 10)
The Write Buffer command is followed by a number of data writes,
which load the endpoints buffer. The data must be organized in the
same way as described in the Read Buffer command. The first byte
(reserved) should always be ‘0’. As in the Read Buffer command,
the data can be split up into different I
2
C data transactions.
WARNING:
There is no protection against writing or reading over a buffer’s
boundary or against writing into an OUT buffer or reading from an IN
buffer. Any of these actions could cause an incorrect operation. Data
in an OUT buffer are only meaningful after a successful transaction.
Clear Buffer
Command
Data
: F2h
: None
When a packet is received completely, an internal endpoint buffer
full flag is set. All subsequent packets will be refused by returning a
NAK. When the microcontroller has read the data, it should free the
buffer by the Clear Buffer command. When the buffer is cleared new
packets will be accepted.
Validate Buffer
Command
Data
: FAh
: None
When the microprocessor has written data into an IN buffer, it should
set the buffer full flag by the Validate Buffer command. This indicates
that the data in the buffer are valid and can be sent to the host when
the next IN token is received.
