2. Getting Started 

Overview 

The IDB-HC08AP Evaluation Board may be used as a standalone 
application or with a MON08-based emulator/programmer (host mode). 

Standalone Mode 

The IDB-HC08AP Evaluation Board comes with the microcontroller pre-
programmed with a sample application. When working in standalone 
mode, the sample application configures the A/D peripheral to convert on 
the A/D channel connected to the potentiometer and displays the results 
on the LEDs. By pressing the PTA6 push button, the DIP-switches status 
is diplayed on the LEDs instead. 

In order for the IDB-HC08AP Evaluation Board to work in standalone 
mode, the MON08 connector’s pins must be jumpered as shown below 
(factory setting).

Additionally, you must verify that the board’s other jumpers are set 
correctly. 

 

 

Make sure that the “OSC SEL” (J7) jumper selects either the “5V” 
position or the “3.3V” position. This is needed to enable the on-board 
16-MHz oscillator with the correct signal voltage. If the microcontroller 
works at 3.3 V, the “OSC SEL” jumper must select the “3.3V” 
position; if the microcontroller works at 5.0 V, the “OSC SEL” jumper 
must select the “5V” position.  

 

Make sure that all of the “LED ENABLE” jumpers (J8) and the 
“POTENTIOMETER ENABLE” jumper (J10) are inserted. 

 

Make sure that the pre-programmed sample device is in the 
appropriate socket on the board. Finally, power up the board. The 
IDB-HC08AP Evaluation Board can be powered either via the 
“UNREG. VDD” connector (J3) or the “REG. VDD” connector (J4). 

 

The “UNREG. VDD” connector accepts 9-12 V DC, 200-mA wall plug-in 
power supply with a 2.1 mm pin and sleeve plug with positive in the 
center and sleeve as ground. When powering the board through this 
connector, make sure the “VDD SOURCE” jumper (J5) selects the 
“UNREG.” Position. The “UNREG. VDD” voltage is internally regulated to 
5 V DC.
