To Set A Permanent Breakpoint - HP 64746 User Manual

To set a permanent breakpoint

• When displaying memory in mnemonic format, position the mouse pointer over the
program line at which you wish to set the breakpoint and click the select mouse
button. Or, press and hold the select mouse button and choose Set/Clear Software
Breakpoint from the popup menu.
• Place an absolute or symbolic address in the entry buffer; then, choose
Breakpoints→Permanent ()
• Using the command line, enter the modify software_breakpoints set <address>
permanent command.
Permanent breakpoints are available if your version of HP 64700 system firmware
is A.04.00 or greater.
The breakpoints feature must be enabled before individual breakpoints can be set.
Note that software breakpoints only stop program execution at memory locations
which contain instruction opcodes (not operands or data).
When displaying memory in mnemonic format, asterisks (*) appear next to
breakpoint addresses. An asterisk shows the breakpoint is active. Also, if
assembly level code is being displayed, the disassembled instruction mnemonic at
the breakpoint address will show the breakpoint instruction.
