[Description of each area]

(1) Information display area

(a) First layer

This layer displays the task information (e.g. Task Name and ID) of the RI850V4.

This layer consists of the following items.


Task Name	An icon indicating the current status of the task and the name of the task are shown in the following format. Icon Name Note that if the name of the task is undefined, the name will appear as "ID".
		DORMANT state
		READY state
		RUNNING state
		WAITING state
		SUSPENDED state
		WAITING-SUSPENDED state
ID	The ID of the task is shown.
Status	The current state of the task is shown.
	Dormant	DORMANT state
	Ready	READY state
	Running	RUNNING state
	Waiting	WAITING state
	Suspended	SUSPENDED state
	Waiting-Suspended	WAITING-SUSPENDED state
Wait Factor	The task wait factor (type of WAITING state, object ID and attribute of WAITING state) are shown in the following format. Type (ID) Attribute Note that if the current state of the task is other than WAITING state or WAITING-SUSPENDED state, "--" appears. If the WAITING state type is sleeping state or delayed state, then "(Object ID)" is not shown.
	[Type of WAITING state]
	SLP	Sleeping state
	DLY	Delayed state
	SEM	WAITING state for a semaphore resource
	FLG	WAITING state for an eventflag
	SDTQ	Sending WAITING state for data queue
	RDTQ	Receiving WAITING state for a data queue
	MBX	Receiving WAITING state for a mailbox
	MTX	WAITING state for a mutex
	MPF	WAITING state for a fixed-sized memory block
	MPL	WAITING state for a variable-sized memory block
	[Attribute of WAITING state]
	ANDW	AND waiting condition
	ORW	OR waiting condition
	TMO	Waiting for timeout
	FIFO	FIFO order
	PRI	Task priority order
Wait Data	The request conditions triggering the task's transition to WAITING state are shown. Note that if the current state of the task is other than waiting state for an eventflag, sending waiting state for a data queue, or waiting state for a variable-sized memory block, "--" is shown.
	Wait bit pattern	Waiting state for an eventflag
	Data element to be sent to the data queue	Sending waiting state for a data queue
	Memory block size to be acquired	Waiting state for a variable-sized memory block
Time Left	The time left until the delayed state is released (in milliseconds) is shown. Note that if the task is waiting forever, "TMO_FEVR" appears. If the current state of the task is other than WAITING state or WAITING-SUSPENDED state, "--" appears.
Interrupt	The current interrupt state of the task is shown.
	Disable	All interrupts are disabled.
	Enable	All interrupts are enabled.
Current Priority	The current priority of the task is shown.
Task Start Address	The start address of the task is shown.
Current PC	The current PC value of the task is shown.
Current Task SP	The current SP value of the task is shown.
Task Stack Area	The start address, end address, and size (in bytes) of the task stack are shown in the following format. Start address - End address (Size)
Initial Priority	The initial priority of the task is shown.
Suspend Count	The suspension count of the task is shown.
Wakeup Count	The wakeup request count of the task is shown.
Activate Count	The activation request count of the task is shown.
Attribute	The attributes of the task (coding language of task, initial activation state of task, initial preemption state of task and initial interrupt state of task) are shown in the following format. Coding language Initial activation state Initial preemption state Initial interrupt state
	[Coding language of task]
	TA_HLNG	C language
	TA_ASM	Assembly language
	[Initial activation state of task]
	TA_ACT	READY state
	Nothing displayed	DORMANT state
	[Initial preemption state of task]
	TA_DISPREEMPT	Preemption is disabled at task activation.
	Nothing displayed	Preemption is enabled at task activation.
	[Initial interrupt state of task]
	TA_DISINT	All interrupts are disabled at task activation.
	TA_ENAINT	All interrupts are enabled at task activation.
Extended Information	The extended information of the task is shown.
Tex Start Address	"--" is shown.
Tex Status	"--" is shown.


Tex Request Pattern	"--" is shown.
Tex Executing Pattern	"--" is shown.
Tex Attribute	"--" is shown.

Remarks 1. Double-clicking a task information cell (e.g., Object Name or ID) displays the source file of the task in the Editor panel and moves the caret to the relevant location.

2. Double-clicking the task information cell for Current Task Stack SP or Task Stack Area displays the contents of the task stack in the Memory panel and moves the caret to the relevant location.

(b) Second layer

This layer displays the locked mutex information (e.g., mutex name or ID) only when a task locks a mutex.

See the [Mutex] tab for details about locking mutex information.
