3.2 OX16PCI954 Serial Controller
The PMCSIO uses an OX16PCI954 single chip PCI solution to offer serial expansion functions on a
PMC module. It is a dual function PCI device offering four ultra-high performance OX16C950 UART's,
and a local bus which is interfaced to the OX16C954 Local Bus Serial Controller.
Each channel in the OX16PCI954 offers data rates up to 15Mbps (realisable on the PMCSIO as
1Mbps on RS232 or 12.5Mbps on RS422/485) and 128 byte deep transmitter and receiver FIFO's.
Deep FIFO's reduce CPU overhead and allow utilisation of higher data rates.
Each channel is software compatible with the widely used industry-standard 16C550 devices and
compatibles as well as the OX16C95x family of high performance UART's. In addition to increased
performance and FIFO size, the UART's also provide the full set of OX16C95x enhanced features
including automated in-band flow control, readable FIFO levels etc. - see section "3.3 OX16C954
Serial Controller (page 5)".
The efficient 32-bit, 33MHz target-only PCI interface is compliant with version 2.2 of the PCI Bus
Specification and version 1.0 of PCI Power Management Specification.
For full flexibility, all the default register values can be overwritten using the EEPROM connected via
the Microwire serial interface. To enhance device driver efficiency and reduce interrupt latency,
internal UART's have multi-port features such as shadowed FIFO fill levels, a global interrupt source
register and Good-Data Status, readable in four adjacent DWORD registers visible to logical functions
in IO space and memory space.

3.3 OX16C954 Serial Controller
The PMCSIO uses an OX16C954 four-channel ultra-high performance UART connected via a local
bus to an OX16PCI954. This offers data rates up to 15Mbps (realisable on the PMCSIO as 1Mbps on
RS232 or 12.5Mbps on RS422/485) and 128 byte deep transmitter and receiver FIFO's. Deep FIFO's
reduce CPU overhead and allow utilisation of higher data rates.
It is software compatible with the widely used industry-standard 16C550 type devices and compatibles,
as well as other OX16C95x family devices. In addition to increased performance and FIFO size, the
OX16C954 also provides enhanced features including improved flow control. Automated software flow
control using Xon/Xoff and automated hardware flow control using CTS#/RTS# and DSR#/DTR# can
be used to prevent FIFO over-run. Flow control and interrupt thresholds are fully programmable and
readable, enabling programmers to fine-tune the performance of their system. FIFO levels are
readable to facilitate fast driver applications.
The addition of software reset enables recovery from unforeseen error condition allowing drivers to
restart gracefully.
The OX16C954 is ideally suited to industrial applications, such as high-speed multi-port functions that
enable users to take advantage of the maximum performance of analogue modems or ISDN terminal
adapters. It is also suitable for any equipment requiring high speed RS232/RS422/RS485 interfaces.
3.4 Serial Clocks
Two oscillators are provided: 1.8432MHz and 50MHz. When used at 1.8432MHz and the UART set to
16C550 mode (via configuration switch) the PMCSIO will behave like and octal 16C550 UART with
operation at all the standard PC baud rates up to 115kbps. This is designed be used in systems where
enhanced drivers are not available.
When used at 50MHz, with the UART's set to enhanced mode and used with the Oxford
Semiconductor drivers variable baud rates up to 12.5Mbps are available - see section "Appendix B Baud Rate Settings (page 17)" for further details.
3.5 Serial Buffers
MAX3245E buffer chips are used for the RS232 channels. These have the following properties:
– 3 drivers and 5 receivers, one IC per channel.
– Maximum data rate of 1Mbps.
– Single 5V operation.
– ±15kV ESD protected.
MAX1486 buffer chips are used for the RS422/485 channels. These have the following properties:
– 1 driver and one receiver, two IC's per channel.
– Maximum data rate of 12.5Mbps.
– Single 5V operation.
– 10 pin µMAX package.
– Selectable full/half duplex.

3.7 EEPROM
The PMCSIO is fitted with 128bytes of EEPROM using a 93C46 device, which is supplied preprogrammed by BVM.
The contents of the EEPROM are read by the OX16PCI954 on coming out of reset and are used to
set up the control registers after reset, allowing the following to be set:
• PCI interface configuration.
• PCI Subsystem and Subsystem Vendor ID.
• Various other configuration parameters.
See section "7.2 Configuration EEPROM (page 14)" and "A.1 OX16PCI954 PCI Quad UART (page
16)" for further details.

3.8 Power Management
The OX16PCI954 is PCI power management 1.0 compliant. In power saving mode the OX16PCI954
will consume 40mA (as opposed to 120mA). The OX16C954 has a power saving mode and will
consume 10mA (as opposed to 20mA).
The MAX4245E RS232 transceivers have an auto-shutdown mode where if there is no activity for 30
seconds they enter a low power state. Their supply current drops from 1mA to 1µA. The autoshutdown feature may be disabled, via a switch, if required.
3.8.1 PME Generation from RI
MIO2 on the OX16PCI954 can be programmed via either EEPROM or device driver to generate a
PME event when the RI signal is asserted by any channel. This feature is enabled/disabled by SW2 see section "5.3.5 SW2 (4) - PME Enable (page 10)".
The feature is not enabled in the PMCSIO EEPROM, as the Oxford Semiconductor drivers do not
currently support this function.
3.8.2 RS232 Power Control
The MIO pins can be used to control the power state of the RS232 transceivers via SW2 - see section
"5.3.4 SW2 (2 & 3) - Low Power Selection (page 10)".
The selection of which MIO pins controls which channels is via PCB LK7 - see section "5.2 Link
Settings (page 9)".
LK7 open (default) gives the following mapping: MIO4 to channels 0 & 1; MIO5 to channels 2 & 3;
MIO6 to channels 4 & 5; MIO7 to channels 6 & 7.
LK7 made gives MIO0 to channel 0, MIO1 to channel 1, ..... MIO7 to channel 7.
The EEPROM is set up to support MIO4, MIO5, MIO6 and MIO7 controlling power saving.
MIO0..MIO3 are unused (saving MIO2 to be used for PME if required) and MIO8..MIO11 used to
interrupts from the second quad UART.
The standard Oxford Semiconductor drivers do not support selection of power saving by use of the
MIO signals, but auto shutdown mode may still be used.

7. Programming
7.1 Windows® Driver Disc
BVM can supply a disk containing the OX16PCI954 and OX16C954 Serial Controller driver files for
Windows® from Oxford Semiconductor along with BVM installation files. The BVM installation files will
ensure that the correct driver configuration is selected upon installation.
Windows® 95, 98, NT4.0 and 2000 are currently supported using the serial ports in their enhanced
mode i.e. variable baud rates and large data FIFO's. Support for other operating systems should be
built in, as the UART's will appear to be standard 16C550 UART devices.
The standard drivers from Oxford Semiconductor for Windows® 95, 98 and NT4.0 do not support
RS485 driver enable (via the DTR line), power saving or power management. The source code is
available from Oxford Semiconductor, so modifications are possible. Control of the RS485 driver
enables, by setting bits in the OX16PCI954 and OX16C954 control registers could be based upon the
PCI subsystem ID enabling automatic identification of RS422/485 channels.
The standard Windows® 2000 drivers from Oxford Semiconductor do support RS485 driver enable
(via the DTR line), but not power saving or power management.
7.2 Configuration EEPROM
The EEPROM contains the BVM PCI Subsystem Vendor ID, which is 15C0 (hexadecimal) and the PCI
Subsystem ID's, which are 0110 (hexadecimal) for the OX16PCI954 with RS232 or 0111
(hexadecimal) for the OX16PCI954 with RS422 and 0112 (hexadecimal) for the OX16C954 with
RS232 or 0113 (hexadecimal) for the OX16C954 with RS422. Use of these ID's in addition to the
standard Oxford Semiconductor OX16PCI954 Serial Controller ID allows selection of the Oxford
Semiconductor driver via the BVM supplied installation files.
The EEPROM is supplied pre-programmed by BVM, but the OXPROM.EXE programming utility is
available from BVM if it proves necessary to reprogram the EEPROM memory device.
7.3 Diagnostic Software
Also supplied on the Windows® Driver Disc is a modified Oxford Semiconductor diagnostic utility for
the OX16PCI954 and OX16C954 Serial Controllers on the PMCSIO running under DOS. Follow the
utility instructions to check the PMCSIO.
The diagnostic utility requires serial loop-back connectors to function. The connections for these on 9way D-type connectors is shown below.

Appendix B - Baud Rate Settings
This Appendix lists the "higher speed" baud rates available on the PMCSIO8. This is using just the
extra divisor (1 to 31.875) and CLK "DIV 1" or "DIV 4" options available on the quad UART part.
A standard 16550 UART would use CLK "DIV 4" @ 1.8432MHz giving a top baud rate of 115.2Kbps
and generate other baud rates using the standard UART divisor register.
With the PMCSIO8 @ 50MHz, 27.125 would be placed in the pre-divisor register giving 50/27.125 ~
1.8432MHz making the UART appear to be a standard clocked UART.
