Functional Features

Compatibility VMEbus-compliant dual high-profile I/O connector type: Dual 64-pin connector, DIN 41612

I/O Organization: Eight I/O ports; eight bits wide.

Addressable to any address within the short supervisory or short unprivileged I/O mapping.

Addressing scheme:

Eight ports can be individually addressed on 8-bit or 16-bit boundaries.

Built-in Tests

Output data can be read back in real-time or off-line mode.

Offline mode can be enabled by writing to the Control and Status Register (CSR) to set the test mode bit.

When test mode is enabled, all outputs are tri-stated (TRI-STATE).

Two test mode bits are provided so that each connector I/O (32-bit) can be tested independently if necessary.

Fault LED:

The Fault LED illuminates at power-up and system reset.

It can be extinguished under program control after successfully performing diagnostics.
