10.1 Features
The TMP19A44 has a built-in 8-channel DMA Controller (DMAC).
The DMAC of the TMP19A44 has the following features:
(1) DMA with 8 independent channels
(2) Two types of requests for bus control authority: With and without snoop requests
(3) Transfer requests: Internal requests (software initiated)/external requests (external interrupts,
(4) Transfer mode: Dual address mode
(5) Transfer devices: Memory space transfer
(6) Device size: 32-bit memory (8 or 16 bits can be specified using the CS/WAIT controller); I/O of 8,
(7) Address changes: Increase, decrease, fixed, irregular increase, irregular decrease
(8) Channel priority: Fixed (in ascending order of channel numbers)
(9) Endian switchover function
interrupt requests given by internal peripheral I/Os, and requests given by the DREQ pin)
16 or 32 bits
(eight interrupt factors, INTDMA0 through INTDMA7)
Requests given by the DREQ pin:
