2.6

UART Interface

The UART interface provides a 550- and 950-compatible

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.

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

section 4.3. The functional use of the EEPROM is

discussed in section 10.

2.8

Software Drivers

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.
