SDS is active during channel B2 on IOM
and MON1. The third example shows a strobe signal for 2B+D channels which is used
e.g. at an IDSL (144 kbit/s) transmission.

The IOM
SMINT
The MONTIOR channel data can be controlled by the bits in the MONITOR control
register (MON_CR). For the transmission of the MONITOR data one of the 3 IOM
channels can be selected by setting the MONITOR channel selection bits (MCS) in the
MONITOR control register (MON_CR).
The DPS bit in the same register selects between an output on DU or DD respectively
and with EN_MON the MONITOR data can be enabled/disabled. The default value is
MONITOR channel 0 (MON0) enabled and transmission on DD.
The MONITOR channel of the T-SMINT

• As a master device the T-SMINT
• As a slave device the T-SMINT
The MONITOR channel operates according to the IOM
Note: In contrast to the NTC-T, the T-SMINT
2.3.3.1
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.
