Using the 166Bug Debugger

By using one of the offset registers, the disassembled code addresses can be made to match the listing file addresses as follows:

Port Numbers

Some 166Bug commands give you the option to choose the port to be used to input or output. Valid port numbers which may be used for these commands are as follows:

1.MVME166 EIA-232-D Debug (Terminal Port 0 or 00) (PORT 1 on the MVME166 J9 connector). Sometimes known as the "console port", it is used for interactive user input/output by default.

2.MVME166 EIA-232-D (Terminal Port 1 or 01) (PORT 2 on the MVME166 J9 connector). Sometimes known as the "host port", this is the default for downloading, uploading, concurrent mode, and transparent modes.

Note

These logical port numbers (0 and 1) are shown in the pinouts of the MVME166 module as "SERIAL PORT 1" and "SERIAL PORT 2", respectively. Physically, they are all part of connector J9.
