0   In   IRQ Any Power Button (active low) x
1   In   IRQ Falling  
2   Out       USB: Renesas RST_N x
3   In   IRQ Falling USB: Renesas INT x
4   Out       CAMERA: I2C? OF sets low - setting high power up 4mA  
5   Out       OF sets low - setting high power up 23mA  
6   Out       CAMERA: I2C? OF sets low - setting high=no effect - no power change  
7   Out       OF sets high - setting low=no effect - no power change
