Monitor12 (MON12) User Manual 05/30/01

The SWI instruction cannot be executed in user code because the monitor program

uses the SWI vector. Breakpoints can only be used in RAM memory locations.

NOTE:

Breakpoints should not be set on branch, jump, JSR, or test and branch

instructions. Setting a breakpoint on these types of instructions may prevent

the Proceed command from operating correctly.

COMMAND FORMATS DESCRIPTION

BR Display all current breakpoints.

BR <address> Set breakpoint.

BR <addr1> <addr2>... Set several breakpoints.

BR - Remove all breakpoints.

BR -<addr1> <addr2>... Remove <addr1> and add <addr2>.

BR <addr1> - <addr2>... Add <addr1>, clear all entries, then add <addr2>.

BR <addr1> -<addr2>... Add <addr1>, then remove addr2>.
