5. Notes
5.1. Analysis of real time trace results
When the trace type is Branch, observe the following restriction on the result of real time trace,
depending on the setup condition or the occurred breakpoint setting.
" When tracing up to the time point when the breakpoint occurs
When the real time trace result is displayed in the bus mode, the trace data at occurrence of the
breakpoint is listed as below. The trace data at Address: FFFF9000 indicates that a break
function has occurred. It does not indicate an occurrence of branch caused by the user program.
Trace data indicating break occurrence
The trace data at Address: FFFF9000 indicates that a break function
has occurred.
For the bus mode display, Address, ST and other fields, see the PD32R Help.
5.2. Zone time measurement error
The zone time measurement function is implemented based on the trace data output from the MCU.
To output a unit of trace data information, the MCU operation clock frequency count shown below is
required. Thus, the zone time measurement result generates a measurement error from the actual
MCU execution time.
A unit of trace data refers to the following information:
(a) Single branch information arising during program execution
(b) Single data access information
According to the trace mode setting, the trace data output from the MCU are described below:
Trace Mode Setting Trace Data Output from MCU
Branch (a) Only branch information
Data (b) Only data access information
Mix(Branch Priority) (a)Branch information and (b) Data access information
Mix(Data Priority) (b)Branch information and (b) Data access information
