UART Interface
section 4.3. The functional use of the EEPROM is
discussed in section 10.
2.8
Software Drivers
The UART interface provides a 550- and 950-compatible
register set, with all the usual 950 features. It has also
been extended over the normal 950 register set to include
a number of performance-enhancing features.
The UART is completely synchronous with a maximum
baud rate of 12 Mbps. The UART clock can be switched off
to save power, and it also includes an asynchronous wake-
up mechanism.
The OXCFU950 USB host controller is typically driven by
the appropriate Oxford Semiconductor supplied driver. The
UART interface can be driven either by an appropriate
Oxford Semiconductor serial driver or by the default serial
driver of the operating system. The advanced features of
the UART interface are not available to default drivers. See
section 11 for further information.
2.7
EEPROM
The OXCFU950 contains an integral 8-Kbyte EEPROM,
which is used to hold user-configurable CIS and LCR (local
configuration register) data. The EEPROM can be
configured using Oxford Semiconductor software utilities
via a host machine or during board manufacture; see
.
