8.9.14 Tracetm (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>]↵ (direct input mode)

(2) >tm↵

(guidance mode)

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 ≤ trigger, addr1–8 ≤ last program memory address

Examples

 

 

 

Format (1)

 

 

 

>tm -n 116↵

... Sets normal trace mode and sets trigger point to 0x0116.

Format (2)

 

 

 

>tm↵

 

 

 

Normal mode

 

 

Trigger Address : 0

3.address area ...? 1↵

... [1. normal] is selected.

1.normal

2.single delay

Trigger address ? :116↵

 

... Trigger address is input.

>tm↵

 

 

 

Normal mode

 

 

Trigger Address : 0116

3.address area ...? 2↵

... [2. single delay] is selected.

1.normal

2.single delay

Trigger address ? :116↵

 

... Trigger address is input.

1.start

2.middle 3.end ...? 2↵

... Trace sampling area is selected.
