Read/write mask
Masks the R bit in address comparisons.
Size mask
Masks the corresponding SZ bit in address comparisons.
Transfer type mask
Masks the corresponding TT bit in address comparisons.
Transfer modifier mask
Masks the corresponding TM bit in address comparisons.
Read/Write
R is compared with the R/W signal of the processor’s local bus.
Size
Compared to the processor’s local bus size signals.

Transfer type
Compared with the local bus transfer type signals. These bits also define the TT encoding for BDM
memory commands.

Else
Transfer modifier
Compared with the local bus transfer modifier signals, which give supplemental information for each
transfer type. These bits also define the TM encoding for BDM memory commands (for backward
compatibility).
