PK-HC08QY4 User's Manual
Technical Note. The MC68HC908QY device (like all devices of the HC08 family) features a
monitor code which, through a serial communication line, allows the programming and the
in-circuit debugging of the user application.
The monitor code is executed in “monitor mode”; the user application is executed is “user
mode”. To enter the monitor mode some microcontroller lines must be properly driven (for
further details please refer to the microcontroller’s data sheet).
The PK-HC08QY4 “USB to MON08 Interface” section groups the circuitry needed to
generate the required signals to enter the monitor mode and to communicate with the host
PC’s USB port. In particular, to enter the monitor mode, the “USB to MON08 Interface”
circuitry generates/handles the following signals:
§ An high-level voltage signal (V TST = 8.2 V) on the PTA2/IRQ pin of the microcontroller;
3
§
§
§
§
§
A reset signal on the PTA3/RST pin of the microcontroller;
The PTA1 and PTA4 pins of the microcontroller are driven to the following levels:
PTA1 = 1, PTA4 = 0;
A power supply line to drive the V DD pin of the microcontroller to 0 V or 5 V;
A single-wire, bidirectional serial communication line on the PTA0 pin of the
microcontroller;
A 28 MHz clock signal on the PTA5/OSC1 pin of the microcontroller (in order to
communicate at a speed of about 27,000 baud over the serial communication line
specified above).
All of the above signals are generated by the MC68HC908JB16 microcontroller through a
USB interface.
Demo Section
The “Demo” section groups push-buttons, a potentiometer, and user LEDs. In detail:
§
Eight user LEDs, together with jumpers to connect them to/disconnect them from the
microcontroller’s Port B pins. All of the microcontroller I/O pins provide the required
current to drive the low-current LEDs used by the starter kit, so no external transistors
are needed.
