GE 68K System Manual Do Utilizador

Use these commands with the 68K Monitor for control and display of process
breakpoints in the system.

The three restrictions with the definition of breakpoints are:
•  You must define breakpoints in code that is in RAM.

−  The program instruction changes to a 68000 family TRAP instruction.

•  You must define all program breakpoints at the beginning of an instruction.
•  Only define breakpoints in a process.

−  If the interrupt mask is non-zero when you enter the breakpoint handler, the

assumption is that the calling routine is an interrupt service procedure (ISP)
and breakpoints are not valid.

Note:

Diagnostic Commands are suspended in order to use breakpoints.
