Figure 13-26: 68HC908LT Family MON08 Pinout
The target GND is connected to the Pin 2 of the target MON08 Header.
The user must pull up the RESET line to target VDD with an external resistor.
The target IRQ line is directly connected to the Pin 6 of the target MON08
Header.
PORTA0 from the target processor is connected to the target MON08 Header
Pin 8, acting as the communications line. The Cyclone PRO pulls up this
signal with a 10K Ohm resistor to the target VDD.
PORTA1 and PORTA2 are used for entering monitor mode. By default the
user may directly bring these signals out to the target MON08 Header.
Alternatively, the user may pull up PORTA1 and pull down PORTC3. In which
case the user does not need to connect these signals to the target MON08
Header. The clock division is fixed Div 4.
Please note that the Cyclone PRO will calculate the proper trim value for the
device being programmed.
