SH-ARC PCI Manual Version 01.00
DEVICE ID = 0x9050h
VENDOR ID = 0x10B5h
CLASS CODE = 0x068000h
SUBSYSTEM ID = 0x00 (not used)
SUBSYSTEM VENDOR ID = 0x00 (not used)
Note : If there are any other PCI cards used in system, which use a PCI-
Parameter-combination identical to the one desciribed above, you have
to use card-specific information (i.e. serial number, controller type ) to
differentiate between the cards. Software routines written in C are
available on disk to read out this data.
For MSDOS a software is included which provides all necessary data in
form of an environment variable. For further information refer to the
Readme file on the floppy disk shipped with the adapter.
A Windows NT driver is included as well.
3.2.1 Address space
Following 4 address spaces are available:
PCI Base
Adress
Registers LOCAL
SPACE COM 20020 COM20022 Register
2 0 MEM / 16BIT / 512 Byte only COM2002x data
register
3 1 IO / 16 BIT / 16 Byte all COM2002x
registers in 2 byte
intervals
4 2 IO / 8BIT / 8 Byte all COM2002x
registers
5 3 MEM / 8BIT / 512 Byte only COM2002x data
register
Local Space 2[3] provides an interface compatible with all ISA bus
adapters equipped with the COM20020 controller.
Local Space 1 enables the use of the COM20022[2] 16-Bit mode. In the
COM20022 the 16-Bit mode is only implemented for the data register. All
other registers remain 8 Bits wide. For these registers the 8 high Bits are
insignificant during 16-Bit accesses by the host PC.
The Local Space 0 and 3 are intended for very fast data transfers from
PC to the SH-ARC PCI adapter. Please contact SoHard GmbH if you
want to use this mode in your own applications. The Windows NT driver
already supports this operation mode.
