page to be transmitted. Logic 1 indicates that additional pages will follow.
5.14 (LP_ACK)
R
Acknowledge.
When this bit is set to a logic 1, it indicates that the link
partner has successfully received its partner’s link code word.
5.13
(LP__MES_PAGE)
differentiate a message page (logic 1) from an unformatted page (logic 0).
5.12 (LP_ACK2)
R
Acknowledge 2.
This bit is used by the NEXT_PAGE function to indicate
that a device has the ability to comply with the message (logic 1) or not
(logic 0).
5.11 (LP_TOGGLE)
R
Toggle
. This bit is used by the arbitration function to ensure
synchronization with the link partner during next page exchange. Logic 0
indicates that the previous value of the transmitted link code word was logic
1. Logic 1 indicates that the previous value of the transmitted link code word
was logic 0.
