Functional description
The ISP1582 is a high-speed USB peripheral controller. It implements the Hi-Speed
USB or the Original USB physical layer and the packet protocol layer. It maintains up
to 16 USB endpoints concurrently (control IN and control OUT, 7 IN and 7 OUT
configurable) along with endpoint EP0 setup, which accesses the setup buffer. The
USB Chapter 9 protocol handling is executed by means of external firmware.
For high-bandwidth data transfer, the integrated DMA handler can be invoked to
transfer data to or from external memory or devices. The DMA interface can be
configured by writing to the proper DMA registers (see
Section 9.4
).
The ISP1582 supports Hi-Speed USB and Original USB signaling. The USB
signaling speed is automatically detected.
The ISP1582 has 8 kbytes of internal FIFO memory, which is shared among the
enabled USB endpoints.
There are 7 IN endpoints, 7 OUT endpoints and 2 control endpoints that are a fixed
64 bytes long. Any of the 7 IN and 7 OUT endpoints can be separately enabled or
disabled. The endpoint type (interrupt, isochronous or bulk) and packet size of these
endpoints can be individually configured depending on the requirements of the
application. Optional double buffering increases the data throughput of these data
endpoints.
The ISP1582 requires 3.3 V power supply. It has 5 V tolerant I/O pads when
operating at V
CC(I/O)
= 3.3 V and an internal 1.8 V regulator for powering the analog
transceiver.
The ISP1582 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: the DMA handler and the DMA
interface.
The firmware writes to the DMA command register to start a DMA transfer (see
Table 47
). The command opcode determines whether a generic DMA or PIO 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 configures the timing and the DMA handshake. Data can be
transferred using either the DIOR and DIOW strobes or by the DACK and DREQ
handshakes. The DMA configurations are set up by writing to the DMA Configuration
register (see
Table 52
and
Table 53
).
For a generic DMA interface, Generic DMA (GDMA) slave mode can be used.
Remark:
The DMA endpoint buffer length must be a multiple of 4 bytes.
For details on DMA registers, see
Section 9.4
