Pin Function
No connect.
25MHz crystal clock connection/or 3.3V Oscillator input.
Crystal/Oscillator should be ±50ppm tolerance.
25MHz crystal clock connection.
No connect.
No connect.
When pin126 is pull-up, the Internal 1.2V LDO controller is
enabled and create 1.2V output with using an external FET.
When pin126 is pull-down (default), the pin 125 is tristated.
Pull-up to enable LDO_O of pin 125. Pull-down to disable LDO_0.
Analog ground.
NC for normal operation. Factory test pin.
