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?
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.
