Data Sheet
2.2.4
The IOM-2 MONITOR channel (see figure 11) is utilized for information exchange
between the SCOUT-DX and other devices connected to the MONITOR channel.
The MONITOR channel data can be controlled by the bits in the MONITOR control
register (MON_CR). For the MONITOR data one of the three IOM channels can be
selected by setting the MONITOR channel selection bits (MCS). 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.
