Automated out-of-band flow control using CTS#/RTS#

and/or DSR#/DTR#

DESCRIPTION

The OXCB950 is a single chip UART solution for either

cardbus or PCI-based serial add-in cards. It is a single

function device, offering memory or IO mapped access to

the ultra-high performance 950-type UART.

has features such as shadowed FIFO fill levels, an interrupt

source register and Good-Data Status, readable in one

DWORD register visible to logical function0 in IO space

and memory space.

This UART is the fastest available PC-compatible UART,

offering data rates up to 15Mbps and 128-byte deep

transmitter and receiver FIFOs. The deep FIFOs reduce

CPU overhead and allow utilisation of higher data rates.

The UART is software compatible with the widely used

industry-standard 16C550 devices and compatibles, as

well as the OX16C95x family of high performance UARTs.

In addition to increased performance and FIFO size, the

UART also provides the full set of OX16C95x enhanced

features including automated in-band flow control, readable

FIFO levels etc.

The efficient 32-bit, 33MHz target-only interface is

compliant with both the cardbus sections of the PC CARD

Standards, and the PCI bus specifications version 2.2 and

version 1.0 of PCI Power Management Specification.

For full flexibility, all the default register values can be

overwritten using an optional Microwire serial EEPROM.

This EEPROM can also be used to provide function access

to pre-configure the UART into enhanced modes prior to

any cardbus/PCI configuration accesses and before control

is handed to generic device drivers.

A set of local registers is available to enhance device driver

efficiency and reduce interrupt latency. The internal UART
