O/
OD
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
O
active SCSI bus terminator etc. Initial signal level on each
pin is “L”. Those pins are available only for PCI bus interface
mode.
IU
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.
