- The CPU checks the state of this port regularly to detect a change in this
signal.
- The Output terminal is controlled by the Output Port of the IC103. When
the Port output is L, the transistor (Q501) on the following level is OFF
and, when the output is H, the transistor is ON. This transistor has open
collector output and it controls external equipment via external pull-up.
13.8.2. Clear Setting SW
- The Clear Setting SW (SW101) is connected to the Input Port of the
GPIO. It is usually at H level and goes to L level, when the SW is
pressed.
- The CPU monitors this Input Port regularly and, if it detects that this SW
is pressed longer than a specified period, the setting values other than
the RTC are returned to factory settings.
13.8.3. LED
- The LED (LED601) has two-color LEDs (red and green). When the
transistor (Q601, Q602) connected to each LED is turned ON/OFF via
the Output Port of the IC103, it controls the ON/OFF of the LED.
