Note that the AVLINK_POWER_UP bit can be set in order to put the ADV7604 in power-down
mode 1 (refer to Section 3.2.1.2).

13.2 AV.link Transmit Module

This module incorporates the functions of the AV.link in the capacity of initiator. The host utilizes
this module to transmit a message to other AV.link devices by setting the mode of the frame, frame
header and data registers (refer to
outgoing message length register. The host then starts the transmission by setting the transmit enable,
AVL_TX_ENABLE, to 1. The AV.link controller starts the transmission process. When the message
transmission is completed, or if an error occurs, the AV.link transmitter module set a relevant status.
