The Trigger_counter_value register characteristics are:
Enables
delaying the indication of triggers to any external connected trace capture
or storage devices. This counter is only eight bits wide and is intended
to be used only with the counter multipliers in the Trigger Multiplier
register, 0x108
. When a trigger is started, this
value, in combination with the multiplier, is the number of words
before the trigger is indicated. When the trigger counter reaches
0, the value written here is reloaded. Writing to this register
causes the trigger counter value to reset but does not reset any
values on the multiplier. Reading this register returns the preset
value, not the current count.
There are no usage constraints.
This register is available in all configurations.
See the register summary in Table 3.114.
Figure 3.110 shows the bit assignments.
Table 3.118 shows the bit assignments.
