A1.4 Set-up of the cross-reference DB
The cross-reference data block contains 256 decimal word addresses.
During a restart, these addresses are stored by the download procedure
on the PCS 830 board. Values for these addresses must be taken from
the CL300 software manual (operation list). The address pointers are
required for indirect addressing. The PCS 830 board addresses must be
specified in the first 3 words (0-2). In the following words (4-255) the
source and/or destination addresses are specified for each word.
Therefore, it is possible to assign the system area command word (DW
14) directly to a flag word without copying the flag word to the data word
and conversely using a transfer command.
The following table shows a section for detailing the structure of the cross-
reference data block.
