MON-12 commands feature direct access to the device internal register map via the
Monitor channel. This means, although the DFE-Q V2.1 features no microcontroller
interface, internal register functions can be directly addressed by use of MON-12
commands.
A MON-12 read request command must be first acknowledged by the DFE-Q V2.1
before a subsequent read request can be triggered. In case of a failure condition the
DFE-Q V2.1 repeats the last outstanding MON-12 answer. MON-12 commands are
prioritized over the other MON classes.
Note: Register read access via MON-12 commands is not possible in state
If U-interface functions are addressed, the value of register LP_SEL determines the
register bank of the channel that is referred to. As a result the desired line port number
must be programmed first in register LP_SEL before any U-interface register can be
accessed. For this reason MON-12 commands may not be issued simultaneously on
different IOM
functions.
For registers that are addressable by MON-12 commands please refer to the
Register Description” on Page
MON-12 commands are of the following format:
• A MON-12 write command comprises 3 bytes, the first byte contains the MON-12
Data Sheet
header, the second byte the register address, the third byte the register value.
'Deactivated'.
However, register read access via MON-12 commands is still possible in state
'Reset' and all active states except 'Deactivated'.
