ICE 6809 is the version of the ICE that supports the 6809 and 6809E processors.
GODIL Jumper Configuration
For the 6809, the GODIL jumpers should be configured as follows:
The black jumper connects the GODIL's GND input to DIL pin 1.
The red jumper connects the GODIL's VCC input to DIL pin 7.
The yellow jumper enables 6809E Mode, see below.
The pins in the top left corner connect to the serial-USB cable.
- A1 is GND
- C1 is Serial Tx (GODIL -> PC)
- A2 is Serial Rx (PC -> GODIL)
These signals are 5V TTL Levels.
6809E Mode jumper
There are some pin-out difference between the 6809 and 6809E processors:
ICE-6809 can emulate either of the processors, and the selection is made via a 6809E Mode jumper shown above:
- Fit the jumper for 6809E mode
- Omit the jumper for 6809 mode
