Section 23 USB 2.0 Host/Function Module (USB)
(5) Pipe Configuration
• On-chip 8-kbyte buffer memory for USB communications
• Up to eight pipes can be selected (including the default control pipe)
• Programmable pipe configuration
• Endpoint numbers can be assigned flexibly to PIPE1 to PIPE7.
• Transfer conditions that can be set for each pipe:
PIPE0:
Control transfer, continuous transfer mode, 256-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 and PIPE7: Interrupt transfer, 64-byte fixed single buffer
Note: When using isochronous OUT transfer, see section 23.5.1, Note on Using Isochronous
OUT Transfer.
(6) Features of the USB Host Controller
• Exclusive communication with a peripheral device with one-to-one connection
• Automatic scheduling for SOF and packet transmissions
• Programmable intervals for isochronous and interrupt transfers
(7) Features of the USB Function Controller
• Control transfer stage control function
• Device state control function
• Auto response function for SET_ADDRESS request
• NAK response interrupt function (NRDY)
(8) Other Features
• Automatic recognition of high-speed operation or full-speed operation based on automatic
response to the reset handshake
• Transfer ending function using transaction count
• DMA transfer termination function
• SOF interpolation function
• Zero-length packet addition function when ending DMA transfers (DEZPM)
• BRDY interrupt event notification timing change function (BFRE)
