message.
Toggle:
1 = Previous value of the transmitted Link Code word equalled 0.
0 = Previous value of the transmitted Link Code word equalled 1.
Code:
This field represents the code field of the next page transmission.
If the MP bit is set (bit 13 of this register), then the code shall be
interpreted as a “Message Page,” as defined in annex 28C of
Clause 28. Otherwise, the code shall be interpreted as an “Unfor-
matted Page,” and the interpretation is application specific.
