DM_NW_MASTER

This contains the length of a block (in 32-bit words) to be written by the MASTER on the command INIT. The block should include all BNL787 defined locations that are ever written to the SSP by the MASTER.

DM_NW_MASTER_SHORT

This contains the length of a block (in 32-bit words) to be written by the MASTER on commands other than the INIT command. This parameter represents the minimum number of words that must be written on giving a command.

DM_NW_STATUS

This contains the length of a block (in 32-bit words) to be read by the MASTER after a command has executed. It includes all words necessary to read a status report from the SSP, i.e. it includes all words up to and including $LMORE_INFO, but excludes counter and histogram addresses that may be read only once per run.

Note that a short status length parameter is not required, since it is only necessary to read one word ($RET_CODE) for this information.

DM_NW_787_FIXED

This contains the total length (in 32-bit words) of the area in DM occupied by the block BNL787 fixed locations. An array DMDAT of length DM_NW_787_FIXED is provided to correspond to the contents of the BNL787 defined locations. For example, the location $COMMAND would correspond to the array element DMDAT(DM_P_COMMAND/4).
