The DIP Switch SW2 is used to select led indication on OSCBK/PWM1 and LVD/PWM2 LEDs. The DIP Switch SW4 is used to connect or disconnect led indication on TxD and RxD LEDs during serial communication. Low Voltage Detection is detected using Pot P1 and resistor ladder network. A 2Kbit EEPROM is used to store data during low voltage detection and recover data stored when micon operates at normal voltage. -
Page 9: Reset Circuitry
7.4 RESET CIRCUITRY The reset circuitry is controlled with a Diode 1N4148, a 0.22uF capacitor and a push button switch SW3. 7.5 NMI CIRCUITRY On the SKP a DIP switch SW1.2 is used to control the NMI pin level. For FDT download, SW1 controls the BOOT and USER mode levels. - Page 10 To disconnect OSCBK/PWM1 led indication, turn ON SW2.2 pin 1(i.e., connect SW2.1 pin to GND). Low Voltage Detection: - Turn ON SW2.2 to use LVD/PWM2 led. This led can be used to indicate low voltage detection or lit according to PWM pulse width on port 8. To disconnect LVD/PWM2 led indication, turn ON SW2.1 pin 1(i.e., connect SW2.1 pin to GND).

Page 11: External User Interface
7.11 EXTERNAL USER INTERFACE The external user interface makes all H8/36912F signals available to the user consistent. The external user interface consists of rows of 12 pin connectors. The diagram indicates which label refers to which row of pins. The external user interface consists of a 26-pin connector. Commonly available 2.54mm (0.100 inch) pitch male headers. - Page 12 If SW1.2 is away from ON position, NMI pin is connected to Vcc and micon is in USER mode. Please refer to diagram 4.c. If SW1.2 is ON, NMI pin is connected to GND and micon is in BOOT mode. Please refer to diagram 4.d.
