Section 21 USB 2.0 Host/Function Module (USB)
(5) Pipe Configuration
• Up to 5 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) and full-speed transfer (12 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
(7) Features of the USB Function Controller
• Both high-speed transfer (480 Mbps) and full-speed transfer (12 Mbps) are supported.
• Automatic recognition of high-speed operation or full-speed operation based on automatic
response to the reset handshake
• Control transfer stage control function
• Device state control function
• Auto response function for SET_ADDRESS request
• NAK response interrupt function (NRDY)
• SOF interpolation function
