This pin is used to input system reset signals.
These pins are used for setting the device operation mode as
listed in the table below.
Interrupt output pin. Either totem pole or open-drain output buffer
can be selected. This pin has an internal pull-up resistor.
Power supply pin
Ground pin
General purpose output ports that can control the external active
SCSI bus terminator etc. Initial signal level on each pin is “L”.
Those pins are available only for PCI bus interface mode.
General purpose input ports. Available only for PCI bus interface
mode.
No connection and unused pins. These pins exist on the only PCI
bus mode. These are internally pulled-up, and do not connect to
the pins.
