Debugger General Information

Caution

Inserting or removing modules while power is applied could damage module components.

31. Turn all equipment power OFF. Refer to the Hardware Preparation section in Chapter 2 and install/remove jumpers on headers as required for your particular application. Jumpers on header J3 affect 166Bug operation as listed below. The default condition is with all eight jumpers installed, between pins 1-2, 3-4, 5-6, 7-8, 9-10, 11-12, 13-14, and 15-16.

The MVME166 may be configured with these readable jumpers. These jumpers can be read as a register (at $FFF40088) in the VMEchip2 LCSR. The bit values are read as a one when the jumper is off, and as a zero when the jumper is on. This jumper block (header J3) contains eight bits. Refer to the MVME166/MVME167/MVME187 Single Board Computers Programmer’s Reference Guide.

The MVME166Bug reserves/defines the four lower order bits (GPI3 to GPI0). The following is the description for the bits reserved/defined by the debugger:
