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 8, acting as the communications line. The MON08 MULTILINK pulls up
this signal with a 10K Ohm resistor to the target VDD.
PORTA7, PORTC0, PORTC1 and PORTC3 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 down PORTA7 and PORTC1, pull up
PORTC0, and pull up/down PORTC3 for clock division. In which casethe user
does not need to connect these signals to the target MON08 Header.
