USB interface (USB)
Introduction
The USB Interface implements a low-speed function interface between the USB and the
ST7 microcontroller. It is a highly integrated circuit which includes the transceiver, 3.3
voltage regulator, SIE and DMA. No external components are needed apart from the
external pull-up on USBDM for low speed recognition by the USB host. The use of DMA
architecture allows the endpoint definition to be completely flexible. Endpoints can be
configured by software as in or out.

Functional description
The block diagram in
For general information on the USB, refer to the “Universal Serial Bus Specifications”
document available at http//:www.usb.org.
Serial interface engine
The SIE (Serial Interface Engine) interfaces with the USB, via the transceiver.
The SIE processes tokens, handles data transmission/reception, and handshaking as
required by the USB standard. It also performs frame formatting, including CRC generation
and checking.
Endpoints
The Endpoint registers indicate if the microcontroller is ready to transmit/receive, and how
many bytes need to be transmitted.
DMA
When a token for a valid Endpoint is recognized by the USB interface, the related data
transfer takes place, using DMA. At the end of the transaction, an interrupt is generated.
Interrupts
By reading the Interrupt Status register, application software can know which USB event has
occurred.
USB Specification Version 1.1 Compliant
Supports Low-Speed USB Protocol
Two or Three Endpoints (including default one) depending on the device (see device
feature list and register map)
CRC generation/checking, NRZI encoding/decoding and bit-stuffing
