8.9.14 Trace

tm
(trace mode display/set)
Function
This command sets and displays a trace mode. It allows you to set the following three trace modes
and a trace trigger point (when a specified address is executed, the TRGOUT pin outputs a pulse).
1. Normal trace mode
The data written to the trace memory is always the latest trace information.
2. Single-delay trigger trace mode
One of the following three trace sampling areas can be specified with respect to the trace trigger
point:
• Start: Trace information is a sample beginning from the trace trigger point.
• Middle: Trace information is a sample from before and after the trace trigger point.
• End: Trace information is a sample all the way up to the trace trigger point.
3. Address-area trace mode
The execution process is traced as instructions inside or outside a specified address range are
executed. This address range can be specified in up to four locations.
Format
(1) >tm <mode> <trigger> [<option>] [<addr1> <addr2> [ ... <addr7> <addr8>]
(2) >tm
Current type setting
1. normal 2. single delay 3. address area . . . ? <1 | 2 | 3>
Trigger address ? : <trigger>
...... (guidance depends on the above selection, see examples)
>
<mode>: Trace mode; -n (normal), -s (single delay), or -a (address area)
<trigger>: Trace trigger address; hexadecimal or symbol (IEEE-695 format only)
<option>: For single-delay trace mode: s (start) / m (middle) / e (end)
For addres-area trace mode: i (in area) / o (out area)
<addr1–8>: Address ranges; hexadecimal or symbol (IEEE-695 format only)
Condition: 0
