Diagnostics and Troubleshooting
Absolute addresses in
the CPU's internal RAM
It is not possible to localize an error in
the program on the basis of the physical
address of the illegal statement.
The "DIR PC" function gives the
absolute start addresses of all
programmed blocks.
The error can then be localized by com-
paring these two addresses.
