P7: Presetting PB (here: -COFF)
Here, the PB must be specified which should be called at the com-
munication start of the corresponding channel. This block must be
generated for customer-specific presettings. This block is of course
available on the floppy disk (once for all three channels) but it contains
only one „HLT“ instruction which will switch the CPU to STOP (status
„1“) with the remark to program the block.
CL300, CL500: block parameters (example - COFF, PB1)
PC600: constant K80XXH (example - COFF, K8001H); xx = block
no.
A2.4 Set-up of the cross-reference data block
A cross-reference data block contains 256 decimal word addresses and
must be specified for each interface (channel). During a restart, these
addresses are stored by the download procedure on the PCS 830.3/1
board. Values for these addresses must be taken from the CL300, CL500,
or PC600 software manual (operation list). The address pointers are
required for indirect addressing. The PCS 830.3 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:
