4.6 USB INTERFACE (USB)
4.6.1 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.

Two or Three Endpoints (including default one)
depending on the device (see device feature list
and register map)
I
CRC generation/checking, NRZI encoding/
decoding and bit-stuffing
I
USB Suspend/Resume operations
I
DMA Data transfers
I
On-Chip 3.3V Regulator

On-Chip USB Transceiver
4.6.3 Functional Description
The block diagram in
Figure 50
, gives an overview
of the USB interface hardware.
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
microcontroller is ready to transmit/receive, and
how many bytes need to be transmitted.
Endpoint
registers
indicate
if
the
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
application software can know which USB event
has occurred.
