To modify registers
•
Choose Modify
→
Register..., and in the dialog box, type in the register name and
new value.
•
Using the command line, modify a register to a new value by typing:
modify register <regname> to <value>
Where <regname> is the name of a processor register, and <value> is an expression
matching the data type of the register (byte or word).
You can enter values into the three FPU control registers using numbers in the
following bases: hexadecimal, decimal, octal, and binary. (You can’t use symbols
for the floating-point registers.)
You can enter values into the eight floating-point registers using either
floating-point or hexadecimal notation. Special values, such as denormals, infinity,
and NaN (Not a Number) can be entered by using hexadecimal notation. The
following are examples of acceptable entries for the floating-point registers:
+12.34e+56
-1.E23
.1e-23
1.2
.7
7654321
0000.000001
7fff0000ffffffffffffffffH
Modifying a register’s contents can help you test the effects of different program
values without the trouble of rebuilding your program code. For example, you
might stop the processor at a certain point (use a software breakpoint), and then
modify a register and run from that point to test the result.
The register is displayed after modification to confirm the change.
The processor must be running to allow modifying registers. See "To display
registers" above for more information.
