Hbreak(Set Hardware Pc Break); Thbreak(Set Temporary Hardware Pc Break)[Icd Mini / Sim] - Epson S5U1C17001C Manual

hbreak
(set hardware PC break)
thbreak
(set temporary hardware PC break)
Operation
Sets a hardware PC breakpoint. The maximum number of hardware PC breakpoints that can be set is 1 to 4 for
the ICD mode, depending on the model, and only 1 for the SIM mode.
When the PC matches the address set during program execution, the program breaks before executing the
instruction at that address. A breakpoint can be set using a function name, line number, or address.
The hbreak and thbreak commands are functionally the same. The following describes the difference:
hbreak: The breakpoints set by hbreak are not cleared by a break that occurs when the set point is reached
during program execution.
thbreak: The breakpoints set by thbreak are cleared by one occurrence of a break at the set point.
When the connection from the debugger is established, the number of the hardware PC breakpoints is
determined by whether 1 write and 1 read are permitted for each IBEx bit. You cannot write 1 for an
unimplemented break number (1: write, 0: read).

Format
hbreak [ Breakpoint ]
thbreak [ Breakpoint ]
Breakpoint: Breakpoint
A breakpoint can be specified with one of the following:
• Function name
• Source file name:line number or line number only
• *Address (decimal, hexadecimal, or symbol)
When omitted, a breakpoint is set at the address displayed on the current PC.
Conditions: 0 ≤ address ≤ 0xfffffe
Usage example
n Example 1
(gdb) hbreak main
Hardware assisted breakpoint 1 at 0xc0001e: file main.c, line 10.
(gdb) continue
Continuing.
Breakpoint 1, main () at main.c:10
A hardware PC breakpoint is set at the position specified using a function name.
When the target program is run, it breaks before executing the first C instruction (expanded to mnemonic) in
main(). The PC on which the program has stopped displays the start address of that instruction (i.e., address
of first mnemonic expanded).
