Notes: Pins labeled as Factory Reserved MUST NOT BE CONNECTED in user applications. These signals are used for
diagnostic and configuration of the ZT 8905 during test.
The TYPE of signal is referenced to the ZT 8905. Out signals are signals the ZT 8905 drives, In signals are signals
that the ZT 8905 receives.
The interrupt levels shown are the most common configuration. Refer to the "Interrupt Architecture" figure in
Chapter 4, "Interrupt Controller," for other possibilities.
The frontplane interrupts are active low inputs that are routed through an inverter before being applied to the
interrupt controller. Pins 2 and 4 are configurable through the BIOS SETUP Utility: Screen 2.
Pin 53 and pin 57 may optionally be disconnected through 0
Ω
resistors at CT1 and CT2.
