Trace information
Running the target program after setting trace mode with this command displays trace information in the [Trace]
window for each instruction executed, or outputs it to a file.
The contents of trace information displayed in a window or output to a file are as follows:
Format of each trace information line
num clk pc code bus_addr/type/data r0 r1 r2 r3 r4 r5 r6 r7 sp ie/il/cvzn src_mix
num: Number of executed instructions (in decimal)
Number of instructions executed since the CPU was reset
clk: Number of execution clocks (in decimal)
Number of execution clocks since the CPU was reset
pc: Address of executed instructions (in hexadecimal)
code: Instruction codes (in hexadecimal)
bus_addr: Accessed memory addresses (in hexadecimal)
type:
Type of bus operation
r8
: Byte data read;
r16
: 16-bit data read;
r32
: 32-bit data read
w8
: Byte data write;
w16
: 16-bit data write;
w32
: 32-bit data write
data: Read/written data (in hexadecimal)
r0–r7: r0–r7 register values (in hexadecimal)
sp: sp register value (in hexadecimal)
ie: IE bit value in psr
il: IL bit value in psr
cvzn: C, V, Z and N bit values in psr
src_mix: Disassembled contents and source codes of executed instructions
