6.2.6 Meanings of DHP trace information items

DHP trace information is displayed in the following way:
It is displayed in a backward chronological order.
It is classified into three groups of task, idle, and OS, where each group of information begins
with the event DISPATCH_E.
The DISPATCH_E line presents numbers in the range 0x00000001 to 0x0000012C in the
DATA1 field. These numbers are the task numbers of tasks.
The time is expressed in seconds and microseconds as a real value with six digits after the
decimal point.
The DHP events and data displayed have the relationships shown in Table 6-7.
<DHP information display example>

brief explanation of which task was executed and of the operation of the operating system (OS)
which took place at the time of task switching.
