Figure 13-10: 68HC908GR4/8 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.
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, PORTB0, and PORTB1 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 PORTB0, pull down PORTA1 and
PORTB1. In which case the user does not need to connect these signals to
the target MON08 Header. The clock division is fixed Div 4.
