Section 17 USB 2.0 Host/Function Module (USB)
(4) Internal Bus Interfaces
• Two DMA interface channels are incorporated.
(5) Pipe Configuration
• Up to 8 kbytes of buffer memory for USB communications are supported
• Up to ten pipes can be selected (including the default control pipe)
• Programmable pipe configuration
• Endpoint numbers can be assigned flexibly to PIPE1 to PIPE9.
• Transfer conditions that can be set for each pipe:
PIPE0:
Control transfer (default control pipe: DCP), 64-byte fixed single buffer
PIPE1 and PIPE2: Bulk transfers/isochronous transfer, continuous transfer mode,
programmable buffer size (up to 2-kbytes: double buffer can be
specified)
PIPE3 to PIPE5:
Bulk transfer, continuous transfer mode, programmable buffer size (up
to 2-kbytes: double buffer can be specified)
PIPE6 to PIPE9:
Interrupt transfer, 64-byte fixed single buffer
(6) Features of the USB Host Controller
• High-speed transfer (480 Mbps), full-speed transfer (12 Mbps), and low-speed transfer (1.5
Mbps) are supported.
• Communications with multiple peripheral devices connected via a single HUB
• Automatic response to the reset handshake
• Automatic scheduling for SOF and packet transmissions
• Programmable intervals for isochronous and interrupt transfers
