Read/write mask. Setting RM masks R in address comparisons.
Size mask. Setting an SZM bit masks the corresponding SZ bit in address comparisons.
Transfer type mask. Setting a TTM bit masks the corresponding TT bit in address comparisons.
Transfer modifier mask. Setting a TMM bit 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.

These bits also define the TT encoding for BDM memory commands. In this case, the 01 encoding
indicates an external or DMA access (for backward compatibility). These bits affect the TM bits.
