3. Hardware Features
Introduction
PK-HC08QY4 is an in-circuit debugger—it programs files into the MC68HC908QY4
microcontroller and offers debugging features like real-time code execution, stepping, and
breakpoints. Its debugging features are achieved thanks to the microcontroller’s integrated
MON08 monitor module.
Contrariwise to traditional in-circuit emulation (where the target application is executed and
emulated inside the emulator), PK-HC08QY4 uses the very same target microcontroller to
carry on in-circuit execution. This means that all microcontroller’s peripherals (timers, A/D
converters, I/O pins, etc.) are not reconstructed or simulated by an external device, but are
the very same target microcontroller’s peripherals. Moreover, the PK-HC08QY4 debugging
approach ensures that the target microcontroller’s electrical characteristics (pull-ups, low-
voltage operations, I/O thresholds, etc.) are 100% guaranteed.
MCU Section
The “MCU” section contains the target microcontroller and the additional circuitry needed for
the correct microcontroller startup. In detail:

An MC68HC908QY4 microcontroller, together with all necessary filter capacitors.
A jumper to select either an on-board generated 28 MHz oscillator frequency or an user
provided clock signal (to be provided to the PTA5/OSC1 pin).
A push-button in the “Demo” section is directly connected to the microcontroller’s reset
pin (PTA3/RST).
All of the microcontroller’s pins are available on the two connectors placed near the
microcontroller.
