Section 25 USB 2.0 Host/Function Module (USB)
(3) All Types of USB Transfers Supported
⢠Control transfer
⢠Bulk transfer
⢠Interrupt transfer (high bandwidth transfers not supported)
⢠Isochronous transfer (high bandwidth transfers not supported)
(4) Internal Bus Interfaces
⢠Two DMA interface channels are incorporated.
(5) Pipe Configuration
⢠On-chip 10-Kbyte buffer memory for USB communications
⢠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, continuous transfer mode, 64-byte fixed-size 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 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
⢠Auto response for reset handshake
⢠Automatic scheduling for SOF and packet transmissions
⢠Programmable intervals for isochronous and interrupt transfers
