1.5 Address frames

1.5.1 Address frames overview

Address frames are used for the identification sequence and for connection
requests. The address frame follows an SOAF and ends with an EOAF. Address
frames shall only be sent outside connections. Address frames shall not be
terminated early. All data dwords in an address frame shall be scrambled.
Table 1.18 defines the address frame format.

The ADDRESS FRAME TYPE field indicates the type of the address frame as
follows:
•
An ADDRESS FRAME TYPE field value of "0" indicates an IDENTIFY
address frame.
•
An ADDRESS FRAME TYPE field value of "1" indicates an OPEN address
frame.
The CRC field contains the CRC value calculated for all the data of an address
frame (data from the beginning of the frame to the byte preceding the CRC field).
If an address frame has an undefined ADDRESS FRAME TYPE, has an incorrect
frame length (longer or shorter than 7 dwords + the CRC length), or has a CRC
error, the recipient discards the frame.
