2.4.5.7 Channelspecific system frames
Channelspecific system frames
System frames are only described by system functions, such as PRESET, scratching, zero
offset external and oblique processing. There are up to seven system frames per channel.
The valid system frames in the channel can be defined via machine data:
MD28082 $MC_MM_SYSTEM_FRAME_MASK (System frames SRAM)
Only system frames required for system functions should be configured, in the interests of
memory space. Per channel, each system frame occupies approx. 1 KB SRAM und approx.
6 KB DRAM. The system frame for PRESET and scratching and the system frame for cycles
are the default. Channel-specific system frames are configured as bit codes, in accordance
with the table below:

Example:
$MC_MM_SYSTEM_FRAME_MASK = 'B001101' means that
there are three system frames; one for PRESET, one for PAROT and one for TOROT and
TOFRAME.
The system frame mask is used to define if the corresponding function has a system frame.
With non-configured frames, in certain circumstances the function will be rejected with an
alarm.
