As shown in Table 17-7, if the DMA is bus master (TT = 01), TM[2:0] indicate the type of
DMA access and provide the DMA acknowledgement information for channels 0 and 1.
Table 17-9 shows TM[2:0] encodings for emulator mode accesses.
The TM signals indicate user or data transfer types during emulation transfers, while for
interrupt acknowledge transfers, the TM signals carry the interrupt level being
acknowledged; see Table 17-10.
Table 17-6. TM[2:0] Encodings for TT = 00 (Normal Access) (Continued)
Table 17-9. TM[2:0] Encodings for TT = 10 (Emulator Access)
Table 17-10. TM[2:0] Encodings for TT = 11 (Interrupt Level)
Table 17-8. TM[
When TT= 01, the TM0 encoding is independent from TM[2:1]
encoding.
