Chapter 12: Emulator/Analyzer Interface Commands
step
If the from address option (defined by --EXPR-- or transfer_address) is omitted,
stepping begins at the next program counter address.
The parameters are as follows:
--EXPR--
An expression is a combination of numeric values, symbols, operators, and
parentheses specifying a memory address. See the EXPR syntax diagram.
FCODE
The function code used to define the address space being referenced. See the syntax
diagram for FCODE to see a list of the function codes available and for an
explanation of those codes.
from
Use this option to specify the address from which program stepping begins.
<NUMBER>
This defines the number of instructions that will be executed by the step command.
The number of instructions to be executed can be entered in binary (B), octal (O or
Q), decimal (D), or hexadecimal (H) notation.
silently
When you specify a number of steps, this option updates the register step
mnemonic only after stepping is complete. This will speed up stepping of many
instructions. The default is to update the register step mnemonic after each
assembly instruction (or source line) executes (if stepping is performed in the same
window as the register display).
transfer_address
This represents the starting address of the program you loaded into emulation or
target memory. The transfer_address is defined in the linker map.
source
This option performs stepping on source lines.
Examples
step <RETURN>
step from 810H <RETURN>
step 5 source <RETURN>
step 20 silently <RETURN>
step 4 from main <RETURN>
