Assign a variable name to each data table register you need. Start at
word 0 of the data table. The data table is read and write accessible.
14.3 Programming BlockĆTransfers
Once you have configured the blockĆtransfer requests, you must
create logic that sets up and initiates the blockĆtransfers. Your
application program must:
D specify the location of the module receiving the blockĆtransfer
request (the target I/O module)
D specify a read or write operation
D specify the length of a blockĆtransfer
D specify the update interval of the blockĆtransfer, either continuous
or nonĆcontinuous
D initiate the blockĆtransfer request to the target I/O module
D write data to or read data from the blockĆtransfer data registers
according to the application's need
D monitor the status bits
See the following sections for detailed information and Appendix D,
Register Assignment Map" for the complete blockĆtransfer status,
control, and data table listing.
