IPC@CHIP Documentation - SC12 @CHIP-RTOS V1.10

B4: Message Exchange wait
B5: -- not implemented --
B6: Suspended (waiting for resume)
B7: Asleep waiting for wakeup
B8 - B15 internal use only
Notes:
■ A task is in "trigger wait" state prior to starting (e.g. RTX_TASK_CREATE_WITHOUT_RUN) or after
termination. A RTX_RESTART_TASK call exits this state.
■ Where as B1, B2, B3, B4 and B7 are mutually exclusive wait conditions, B6 "Suspended" condition can
be added (OR'ed in) to these other wait conditions.
taskCount
This value, ranging from 0 to 10000, provides a rough indication of the amount load placed on the system by
this task. At each execution of the @CHIP-RTOS 1000 Hz real-time interrupt handler, this count is incremented
if this particular task is either currently executing or if the CPU is idle and this task was the most recent task to
be executed. The running count is recorded at 10 second intervals, so a task which is active 100% of the time
would score a taskCountof 10000. (Same true if the task had been sleeping for the last 10 seconds, but it
was the most recently active task ... oh well.)
stackused
This value is the percentage of the task's stack space used. The system presets stack space to all zeroes prior
to starting tasks. The deepest (lowest address) non-zero value on the stack indicates the "high water
mark". This value is only meaningful for tasks created within application programs. DOS programs normally
switch stacks on entry, so this the stack space usage measurement is defeated.
stacksize
This is the total number of bytes in the task's stack space. This value is only meaningful for tasks created within
application programs, due to that DOS programs normally switch stacks on entry.
