APPENDIX A DESCRIPTION OF SPD CHART

(2) If processing continues from coincidence status

• SPD chart

(SWITCH: condition)

[CASE: Status 1]

Processing 1

[CASE: Status 2]

Processing 2

...

...

[CASE: Status n]

Processing n

[default]

Processing 0

(execution)

When status 1: processing 1 → processing 2 → ... → processing n

When status 2: processing 2 → ... → processing n

.....

.....

When status n: processing n

If status does not coincide: processing 0

Example Transmission/reception of serial interface

(SWITCH: transfer mode)

[CASE: 1]

Address transmission

[CASE: 2]

Data transmission

break

[CASE: 3]

Data reception

(execution)

When status 1: address transmission → data transmission

When status 2: data transmission

When status 3: data reception

4. Conditional Loop (WHILE)

The condition indicated by WHILE is judged. If the condition is satisfied, processing is repeatedly executed (if

the condition is not satisfied from the start, the processing is not executed).

• SPD chart

(WHILE: condition)

Processing

Example Buffers key until RETURN key is input

(WHILE: not RETURN key)

Inputs 1 character key

Stores input key to buffer
