Figure 13-18: 68HC908JL Family MON08 Pinout
The target GND is connected to the Pin 2 of the target MON08 Header.
The target RESET line is directly connected to the Pin 4 of the target MON08
Header.
The target IRQ line is directly connected to the Pin 6 of the target MON08
Header.
PORTB0 from the target processor is connected to the target MON08 Header
Pin 10, acting as the communications line. The Cyclone PRO pulls up this
signal with a 10K Ohm resistor to the target VDD.
PORTB1, PORTB2 and PORTB3 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 PORTB1 and pull down PORTB2, and pull
up/down PORTB3 for clock division. In which case the user does not need to
connect these signals to the target MON08 Header.
