USB HARDWARE
The characteristics of USB hardware are as fol-
lows:
I
Complies with the Universal Serial Bus
specification Rev. 1.1
I
Integrated SIE (Serial Interface Engine), FIFO
memory and transceiver
I
Low speed (1.5Mbit/s) device capability
I
Supports control endpoint0 and interrupt
endpoint1 and 2
I
USB clock input must be 6MHz (requires MCU
clock frequency to be 12, 24, or 36MHz).
The analog front-end is an on-chip generic USB
transceiver. It is designed to allow voltage levels
equal to V
DD
from the standard logic to interface
with thephysical layerof the Universal Serial Bus.
It is capable of receiving and transmitting serial
data at low speed (1.5Mb/s).
The SIE is the digital-front-end of the USB block.
This module recovers the 1.5MHz clock, detects
the USB sync word and handles all low-level USB
protocols and error checking. The bit-clock recov-
ery circuit recovers the clock from the incoming
USB data stream and is able to track jitter and fre-
quency drift according to the USB specification.
The SIE also translates the electrical USB signals
into bytes or signals. Depending upon the device
USB address and theUSB endpoint.
Address, the USB data is directed to the correct
endpoint on SIE interface. The data transfer of this
H/W could be of type control or interrupt.
The device’s USB address and the enabling of the
endpoints are programmable in the SIEconfigura-
tion header.
USB related registers
The USB block is controlled via seven registers in
the memory: (UADR, UCON0, UCON1, UCON2,
UISTA, UIEN, and USTA).
Three memory locations on chip which communi-
cate the USB block are:
I
USB endpoint0 data transmit register (UDT0)
I
USB endpoint0 data receive register (UDR0)
I
USB endpoint1 data transmit register (UDT1)
