Name
TM
TT
Transfer type. Compared with the local bus transfer type signals.
00 Normal processor access
01 Reserved
10 Emulator mode access
11 Acknowledge/CPU space access
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.
Transfer modifier. Compared with the local bus transfer modifier signals, which give supplemental information
for each transfer type.
TT = 00 (normal mode):
000 Explicit cache line push
001 User data access
010 User code access
011 Reserved
100 Reserved
101 Supervisor data access
110 Supervisor code access
111 Reserved
TT = 10 (emulator mode):
0xx–100 Reserved
101 Emulator mode data access
110 Emulator mode code access
111 Reserved
TT = 11 (acknowledge/CPU space transfers):
000 CPU space access
001–111 Interrupt acknowledge levels 1–7
These bits also define the TM encoding for BDM memory commands (for backward compatibility).
