DMAC (DMA Controller)
can realize data transfer faster than the micro DMA function by the 900/H1 CPU.
The TMP92CF29A incorporates a DMA controller (DMAC) having six channels. This DMAC
The DMAC has the following features:
3) Various source/destination combinations
4) Transfer address mode
5) Dual-count mechanism and DMA end interrupt
6) Priorities among DMA channels (the same as the micro DMA acceptance specifications
7) DMAC bus occupancy limiting function
8) The DMAC can be used in HALT (IDLE2) mode.
1) Six independent channels of DMA
2) Two types of transfer start requests

Only the dual address mode is supported.
Two count registers are provided to execute multiple DMA transfers by one DMA
DMA requests are basically accepted in the order in which they are asserted. If more
