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.
