ISP1583
Hi-Speed USB peripheral controller
The ISP1583 operates on a 12 MHz crystal oscillator. An integrated 40
× PLL clock
multiplier generates the internal sampling clock of 480 MHz.
8.1 DMA interface, DMA handler and DMA registers
The DMA block can be subdivided into two blocks: DMA handler and DMA interface.
The rmware writes to the DMA Command register to start a DMA transfer (see Table 51).
The command opcode determines whether a generic DMA, Parallel I/O (PIO) or
Multi-word DMA (MDMA) transfer will start. The handler interfaces to the same FIFO
(internal RAM) as used by the USB core. On receiving the DMA command, the DMA
handler directs the data from the endpoint FIFO to the external DMA device or from the
external DMA device to the endpoint FIFO.
The DMA interface congures the timing and the DMA handshake. Data can be
transferred using either the DIOR and DIOW strobes or the DACK and DREQ
handshakes. DMA congurations are set up by writing to the DMA Conguration register
(see Table 56 and Table 57).
For an IDE-based storage interface, applicable DMA modes are PIO and MDMA
(Multi-word DMA; ATA).
For a generic DMA interface, DMA modes that can be used are Generic DMA (GDMA)
slave.
Remark: The DMA endpoint buffer length must be a multiple of 4 bytes.
For details on DMA registers, see Section 9.4.
