products). On these products, the signal connections can be left un-
terminated.
Full-speed (12M bits/s) device operation
16 unidirectional endpoints
Each endpoint capable of supporting control, interrupt, isochronous and bulk
transfer
Programmable endpoint types and FIFO sizes and internal 1120-byte logical
(2240-byte physical for dual-packet mode) shared FIFO storage allow a wide
variety of configurations.
Dual-packet mode of FIFOs reduces latency
USB reset can be programmed to clear device address.
