Table 3: USER_EN Option Settings
Pushbutton Switches
Two push button switches provide momentary active low input for user applications. SW1 and
SW2 are enabled to the HC08 I/O ports by the USER option bank. SW1 and SW2 provide in-
put to HC08 I/O ports PTC6 and PTC5 respectively.
LED Indicators
Indicators LED1 and LED2 are enabled from HC08 I/O ports by the USER_EN option. The
LED indicators are active low and illuminate when a logic low (0V) signal is driven from the
respective MCU I/O port. MCU ports PTF0 and PTF1 drive LED1 and LED2 respectively.
RV1 Potentiometer
A 5k Ω, thumb-wheel potentiometer at RV1 provides variable resistance output for user
applications. The device provides a 0 to VDD (+5V typical) output to the PTB2 input when
enabled.
RZ1 Photocell
A visible-light sensitive photocell (RZ1) with an amplifying OPAMP circuit provides a variable
voltage output for user applications. Circuit output voltage ranges between .5V to VDD typical
and is inversely proportional to light intensity on the surface of the sensor (VDD = Dark).
When enabled, the circuit output voltage is provided to MCU port PTB3 input for user
application.
