DMA Controller (DMAC)
The TMP1942 incorporates a four-channel DMA controller.
Features
(1) Independent 4-channel DMA
(2) Two types of request for control of the bus: with snoop request or without snoop request
(3) Transfer request: Internal transfer request: Start by software
(4) Transfer mode: Dual-address mode
(5) Transfer devices: Memory-to-memory, memory-to-I/O, I/O-to-memory
(6) Device size:
(7) Address change: Increment, decrement, fixed, irregular increment or irregular decrement
(8) Channel priority: Fixed
The DMAC included in the TMP1942 has the following features:
External transfer request: Request by interrupt
32 bits for memory (16 or 8 bits can also be specified using the CS/wait
controller); 8, 16 or 32 bits for I/O
