today I was searching the global RST line and looked more exactly on J66.
10 9 8 7 6
1 2 3 4 (5)
If you look from top the right bottom pin is missing, pinout is as follows:
Pin1 - +3V3
Pin2 - IR-reciever to PIC PIN41
Pin3 - GND
Pin4 - D7 LED(green) to PIC PIN2
Pin6 - GND
Pin7 - D8 LED(green) to PIC PIN38
Pin8 - GND
Pin9 - IR-leds to PIC PIN37
Pin10 - 12V
guess that the PIC has a ouput for global reset and also an output to activate recovery
does someone know more or can correct me?
update:
J20 I2C lines are also available on XDP1, but lines are without pullups and no activity is visible
Further more the paaring switch is connected to PIC PIN15.
