Data Sheet
2.2.4.1
The MONITOR channel operates on an asynchronous basis. While data transfers on the
bus take place synchronized to frame sync, the flow of data is controlled by a handshake
procedure using the MONITOR Channel Receive (MR) and MONITOR Channel
Transmit (MX) bits. Data is placed onto the MONITOR channel and the MX bit is
activated. This data will be transmitted once per 8-kHz frame until the transfer is
acknowledged via the MR bit.
The MONITOR channel protocol is described In the following section and illustrated in
Figure 32. The relevant control and status bits for transmission and reception are listed
in table 7 and table 8.
