Appendix F. Write Through’s

This driver provides very limited Write Through Support.

It is possible to generate a Write Through by writing to the Data Array used in a read Map Descriptor where the DA_Func keyword is ‘Everything’ provided that the write through results in Dap80-Menu command being sent to the DAP device. This is true for variables whose offsets are between 899 and 1086 in Section Appendix A.3
