[Description of each area]

(1) Information display area

This area displays the system information (e.g. RTOS Name and Version) of the RI850V4.

This area consists of the following items.


RTOS Name	The RTOS name "RI850V4" is shown.
Version	The version of the RI850V4 is shown.
System Time	The system time of the RI850V4 (in milliseconds) is shown.
Interrupt Nest	The nesting level of interrupt processes (including CPU exception processes) is shown.
Dispatching	The system state of the RI850V4 is shown.
	Disable	Dispatch disabled state
	Enable	Dispatch enabled state
CPU Lock	The system state of the RI850V4 is shown.
	Locked	CPU locked state
	Unlocked	CPU unlocked state
System Stack Area	The start address, end address, and size (in bytes) of the system stack are shown in the following format. Start address - End address (Size)
Current System SP	If the processing program is operating on the system stack, the start address of the system stack is shown. If it is running on the task stack, then the current SP value is shown.
Idle Routine Start Address	The start address of the idle routine is shown.
Number of Priority	The maximum priority of the task is shown.
Number of Task	The total number of tasks is shown.
Number of Semaphore	The total number of semaphores is shown.
Number of Eventflag	The total number of eventflags is shown.
Number of Data Queue	The total number of data queues is shown.
Number of Mailbox	The total number of mailboxes is shown.
Number of Mutex	The total number of mutexes is shown.
Number of Message Buffer	"--" is shown.
Number of Fixed-Sized Memory Pool	The total number of fixed-sized memory pools is shown.
Number of Variable-Sized Memory Pool	The total number of variable-sized memory pools is shown.
Number of Cyclic Handler	The total number of cyclic handlers is shown.
Number of Alarm Handler	"--" is shown.
Number of Interrupt Handler	The total number of interrupt handlers/CPU exception handlers is shown.
Number of Initialize Routine	The total number of initialize routines is shown.
Number of Extended Service Call Routine	The total number of extended service call routines is shown.

Remarks 1. Double-clicking the system information cell for System Stack Area or Current System SP displays the system stack contents in the Memory panel and moves the caret to the relevant location.

2. Double-clicking the system information cell for Idle Routine Start Address displays the source file of the idle routine in the Editor panel and moves the caret to the relevant location.

[Context menu]

The context menu displayed in response to a right mouse click differs as follows depending on the area clicked.
