MON08 MULTILINK
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.
Alternatively, the user may pull up the RESET line to target VDD. In which
case the user does not need to connect this signal to 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 10, acting as the communications line. The MON08 MULTILINK pulls up
this signal with a 10K Ohm resistor to the target VDD.
PORTA1, PORTA2 and PORTC1 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 PORTA2, and pull
up/down PORTC1 for clock division. In which case the user does not need to
connect these signals to the target MON08 Header.

PORTB0 from the target processor is connected to Pin 8 of the target MON08
Header. PORTB1 of the target processor is connected to Pin 3 of the target
MON08 header. Together they serve as the data communication lines. The user
