USB 2.0 compliant
— 12 Mbps full-speed (FS) data rate
— USB data control logic:
Seven USB endpoints
— Bidirectional endpoint 0
— Six unidirectional data endpoints configurable as interrupt, bulk, or isochronous
— Endpoints 5 and 6 support double-buffering
USB RAM
— 256 bytes of buffer RAM shared between system and USB module
— RAM may be allocated as buffers for USB controller or extra system RAM resource
USB reset options
— USB module reset generated by MCU
— Bus reset generated by the host, which triggers a CPU interrupt
Suspend and resume operations with remote wakeup support
Transceiver features
— Converts USB differential voltages to digital logic signal levels
On-chip USB pullup resistor
On-chip 3.3 V regulator
– Packet identification and decoding/generation
– CRC generation and checking
– NRZI (non-return-to-zero inverted) encoding/decoding
– Bit-stuffing
– Sync detection
– End-of-packet detection
Features
Modes of Operation
USB module is not functional. Before entering stop1, the internal USB voltage regulator and USB transceiver
enter shutdown mode; therefore, the USB voltage regulator and USB transceiver must be disabled by firmware.
