MVME197LE Functional Description

the BBRAM, TOD Clock memory map description in the Operating Instructions chapter of this manual. The MVME197LE debugger has the capability to retrieve or set the Ethernet address.

If the data in the BBRAM is lost, the user should use the number on the VMEbus P2 connector label to restore it. Refer to the MVME197BUG 197Bug Debugging Package User’s Manual.

The Ethernet transceiver interface is located on the MVME197LE main module, and the industry standard connector is located on the MVME712X transition module.

Support functions for the 82596CA are provided by the PCCchip2. Refer to the 82596CA LAN Coprocessor User’s Manual and to the PCCchip2 chapter in the MVME197LE, MVME197DP, and MVME197SP Single Board Computers Programmer’s Reference Guide for detailed programming information.

SCSI Interface

4

The MVME197LE provides for mass storage subsystems through the industry- standard SCSI bus. These subsystems may include hard and floppy disk drives, streaming tape drives, and other mass storage devices. The SCSI interface is implemented using the NCR 53C710 SCSI I/O controller.

Support functions for the 53C710 are provided by the PCCchip2. Refer to the NCR 53C710 SCSI I/O Processor Data Manual and to the PCCchip2 chapter in the MVME197LE, MVME197DP, and MVME197SP Single Board Computers Programmer’s Reference Guide for detailed programming information.

SCSI Termination

The system configurer must ensure that the SCSI bus is terminated properly. On the MVME197LE, the terminators are located on the P2 transition board. The +5V power to the SCSI bus termination resistors is provided by the P2 transition board.

Peripheral Resources

The MVME197LE includes many resources for the local processor. These include tick timers, software programmable hardware interrupts, watchdog timer, and local peripheral bus timeout.

Programmable Tick Timers

Six 32-bit programmable tick timers with 1 μsec resolution are provided, two in the BusSwitch, two in the VMEchip2, and two in the PCCchip2. The tick timers can be programmed to generate periodic interrupts to the processor.
